Ubuntu :: Network Broken After Updates?
Mar 4, 2011
There's a problem with the latest updates. First I allowed the 32-bit version to update under VirtualBox, and now cannot boot with the new kernel. The old kernel works, so it's not really a problem. BUT:
Then, I allowed update on the real desktop, and now the network disappeared. sudo /etc/init.d/networking restart shows a very short message about eth0=eth0 and does nothing.(I cannot copy&paste, because the network is not working under Ubuntu. Now I'm under Windows, the network works (I can post).) Atheros L1 Gigabit Ethernet 10/100/1000Base-T Controller PCI bus 2, dev 0, func 0

After I installed Lucid, everything was fine than I went ahaed and did the customary updates after the install but and when I rebooted, my top panel got messed up. Basically nothing on the right hand is working. It either appears as doubled and it doesn't appear at all. I've attached a screenshot so that you can see what I'm talking about.

I just did a clean install of OpenSuSE 11.0 and performed all the available updates as well. After rebooting when I try to SSH into my SuSE workstation I get:
PuTTY Fatal Error
Server unexpectedly closed network connection
I don't see anything relevant in /var/log/messages. I've tried rebooting and restarting the SSHD service.

Yum is unable to access any packages in the F15 updates repository. When I manually download and browse the repo filename list (http://ftp.jaist.ac.jp/pub/Linux/Fed...ateinfo.xml.gz) it seems that the files are listed as being available from the Fedora *5* address, which is obviously incorrect. This issue seems to have been going on for a few weeks now.

I just re-installed on a third computer Fedora 12 from the DVD iso that has been used on many machines. But in the past 3 days I am getting the following message. This is on 2 different downloads of the iso also. It hasn't ever happened to me in the past.
Here is the error:

I am running Squeeze AMD64 and install updates every couple of days. I installed the latest batch yesterday and got a "restart system" message, so rebooted. The usual messages scrolled past for a while, then the screen went blank, and that was it. I tried a couple of times with same result. I booted into maintenance mode to try to find the cause of the problem. Looking at /var/log/messages there is some strange activity going on. Unfortunately I can't easily paste the relevant portion of the file into this posting as the network isn't working (I am posting this from a laptop), but roughly what I am seeing is this:
PGD <some stuff>
CPU 0
Modules linked in: <long list of modules>
Pid, 1841, comm: Xorg Not Tainted <some stuff>
<about 20 lines of assorted values>
--[end trace <long hex number>]
and this repeats several times (presumably stopping when I hit the reset button). Sometimes it's CPU 0 and sometimes CPU 1, it mostly involves Xorg in Pid line, and apart from the first instance mostly reports Xorg Tainted.
I could just reinstall but would rather repair as it would be both quicker and more instructive.

After recently installing Linux Mint 10 I have tried to install the updates it says and everytime it tells me I have to fix broken packages first. I have been into something that tells me there is no broken packages. What can I do?

I once had rock solid systems running opensuse. The hardware hasn't changed, but the system certainly has. The last time I could describe my systems as rock solid, was before the more or less forced move to KDE4. They've been anything but solid since, and it seems the more updates, the more things that get broken. I have two systems involved (a third is my server, so far unaffected). I have a desktop system that I built (4 years ago) on an Asus motherboard using an Nvidia chipset. The second is a laptop, a Lenovo T500 with both ATI and Intel graphics.
First, the upgrade to 11.4 broke the ATI video on the laptop. Tried everything, the proprietary ATI driver as well as the radeon driver. Learned online about adding the 'nomodeset' option, which got the video to work...if I could put up with random freezes, jerky video, and a desktop that refreshed in waves. Broken. Period. Gave up, switched the system one last time to the Intel graphics and never looked back. The ATI graphics on that laptop is unusable. Fortunately, I had the option of Intel or the laptop would still be unusable to me.
On the other hand, the upgrade to 11.4 on my desktop system running nvidia graphics went without a hitch. I was even pondering the idea of seeing if I could swap out the ATI graphics on the laptop for an Nvidia board. Then came this weekend's updates, which broke the Nvidia drivers. Yes, it would still boot up to a desktop, but I had a black desktop background and all of the configuration windows I opened came up completely black. Spent a couple of hours removing/reinstalling drivers. Uninstalled the Nvidia drivers and reinstalled.
Switched to the open source drivers. After numerous attempts, with the system unable to boot to X at all at points, I finally achieved an apparently functioning system with the nouveau driver. If the objective of the developers involved is to drive people away from linux and/or render opensuse unusable, well, they are doing a wonderful job. If I were not the technically inclined individual I am, I would have had no choice with either of these cases but to abandon the operating system for something else. It's ridiculous and counterproductive.

I run XBMC 10.1 (packman version) on openSUSE 11.4 x86_64. After a normal package update (zypper up) last weekend, I can't play none of my DVD folders (VIDEO_TS structure) anymore. When selecting a movie to play nothing happens (XBMC log file message "WARNING: could not find codec parameters for /path_to_movie/VIDEO_TS/VIDEO_TS.IFO"). AVIs still play fine. I reproduced the problem on my laptop too: After the following updates the problem occurs:

I use 10.04 Lucid on my Dell mini10v netbook, it works fine, but the network status icon is broken. When i connect to my wired network, the icon correctly changes to the 2 "arrows" that show that the wired connection is active. But when i dissconnect the wired network, and i connect to my wireless one (or any wireless network), the icon has the "X" (not connected) mark, even thoug the network IS properly connected (i can access internet, local network, etc).

I'm not sure if I have two seperate issues or one inter-related issue. The Network Manager applet wasn't appearing in the tray, found out it wasn't installed. Installed, still didn't appear. Tried installing WiCd, WiCd did appear but couldn't find any networks. I had installed restricted drivers previous, decided it was worth another look. Found that Broadcom STA Wireless Driver wasn't installed. Tried to install, it said it couldn't and said I should review the var/log/jockey which is....excessively long.

Been helping a user who recently upgraded to 11.04 as his networking stopped after the upgrade. One thing I noticed was that he could not get ping to work.Then checked my 11.04 machine and it also fails to ping using Network Tools. I know the network is OK as I am using my Ubuntu machine to write this. Ping from the command line is fine so it is only the Network Tools ping test that appears to be broken.
Asked another Ubuntu 11 user to check his machine and he also cannot get ping to work even though his machine appears to be fine. Again this is only using the GUI tool.I know it is not hardware as I can dual boot and in XP everything is fine and I can ping all my systems. Also I am sharing a folder from my Ubuntu and my Mac shares the folder just fine. The Mac can also ping everything except the Ubuntu box. Command line ping works so it is not a basic network problem.So as far as I can tell the Network Tools ping test is not working. Has anyone else seen this or can confirm that it is broke. How do I report this or get it fixed?

I downloaded the ISO for the network install and burned and booted it just fine. It detected my network card and got a valid ip.When it goes to actually start to install it gives an error saying:cannot retrieve repository metadata and makes mention of some file called repomd.xml
I put the url listed into my browser and it listed all the mirrors and I checked a few of the mirrors to see if they were up and they were.What gives with this? Why doesn't the network installer find the repositories properly?

after I upgraded my SUSE 11.0 to 11.1 many problemes solved themselves. But now there is a new one.
I use openvpn, which always used to work without problems. After upgrading to SUSE 11.1 there is the error message:
"/etc/openvpn/client-suse.sh: line 7: modify_resolvconf: command not found

The shell script is as follows:

Dell Precision Workstation running Suse 11.1 & KDE 3.5 as default O/S, with Suse 11.3 KDE4, Ubuntu 10.04 & Win XP Pro as secondary O/S's.Medion PC with Win XP Pro for those windows apps I have to use (against better judgement but because my clients require it!)
On Friday 6th I was having a play with Apache2 running on the Dell Precision on Suse 11.1. I have had a local development webserver for some time to test websites before uploading them a host server. I had wanted to test the DHCP & DNS functions for some time, and this seemed like a good opportunity. But I ran into some problems and decided to un-install the DHCP & DNS. I intended to install a VM and re-install the Apache server on it, to make it easier to troubleshoot.Unfortunately my internet connection on that box is now broken, but only with the Suse 11.1 install. The other 3 O/S's all work fine, and the rest of my machines are all good. In fact the Suse 11.1 install can communicate across the LAN, and print to both the network printers, it just won't connect to the Internet. Turning off the firewall doesn't do anything, and reconfiguring the NIC in YaST doesn't help.
I suspect that there is a config file somewhere with faulty info, but I can't find it. If searched everything that was changed on that date.I have been searching this forum, LinuxQuestions forums, and Googling for 2 days with no real success. I found some interesting threads which I thought would help but so far no luck. I can ping all the interfaces on my LAN, but anything outside is blocked. I thought it might be in the BT HomeHub but that works fine and all the boxes can connect except with the Precision running 11.1.

I've just installed OpenSuse 11.2 64-bit and, on the whole, I'm pretty happy with it. I'm connected to the network and I am posting this from my new system. However I cannot get any software updates or install new packages
I'm behind a (non-authenticated) proxy and, obviously, Firefox has no problem.
If I use Online Updater I just get error messages like this:
PackageKit Error repo-not-available: Failed to download ./repodata/primary.xml.gz from Index of /update/11.2
(but the site is available in Firefox).
I have tried manual updates through Yast (after setting the proxy) and get pretty much the same thing.
So far I have set the proxy in:
Firefox
/etc/sysconfig/proxy
/etc/PackageKit/PackageKit.conf
Computer -> Yast -> Network Services -> Proxy (That has a test function which confirms it is working).
Applications -> System Settings -> Network Settings (This tells me that the network settings are controlled by NetworkManager and can't be modified by Yast).

I was wondering if anyone else is having trouble getting updates. I ran the software update out of the control center when I first installed 11.4 with the gnome desktop.I ran the yast online update and got what was on there, but now it just gives me error messages, basically it's stating it can't connect to the repositories.

I was running Ubuntu 9.10 on my HP G70 laptop and did an upgrade using upgrade manager to Ubuntu 10.04.
Since I haven't been able to get wifi connection or wired working. The Network Manager applet is missing from the notification area and if I try to run nm-applet manually it says it is already running. I tried killing the process and then running it manually in the terminal and although the process appears to be running it is missing from the panel.
Booting into the live cd has the applet working fine so something in the upgrade process must have failed.
I tried changing the theme to see if it displays in other themes but had no luck.
I also tried to log into kde but kde seems to be broken. When I log into it after the splash screen all I get is a black screen with only my mouse pointer.

I have 2 PC's running FC11. The server is sharing a path /raid/shared.windows and the other is mounting that path.
On the server there is a symbolic link /raid/shared.windows/dir that points to /raid/dir
The problem is that this link is broken when the viewed from the mount point on the other PC.
Is it possible that the link is trying to look at /raid/dir on the other PC, rather then on the server?
If so how do I fix it, such that the symbolic link is linked to the right directory on the server?

I posted this already in the absolute beginner section, but no answer was found, so I thought I might try this place..Long story as short as possible:
- I installed Ubuntu 9.10 for a friend who was fed up with WinXP crashing all the time
- After the install, networks was broken. I could ping sites outside the LAN, could connect to the router via firefox, but NO application could access the web. - The router works just fine, I tried with my own notebook.
- Disabling ipv6 in grub (edit /etc/default/grub and 'sudo update-grub') seemed to solve the problem.
- Then update the standard packages + install restricted extras and boom, Network gone: No ping to sites outside the LAN, no nothing. Still can connect fine to the router and even the remote desktop connection works, connecting over the internet. But that's it.
I have tried setting the mpu to a value recommended by my isp, I have set static ip and dns, I really don't now what to try any more.

I have a dual-boot Compaq CQ60-420US laptop. It can connect wirelessly in Vista without a problem. I have not yet figured out how to connect it wirelessly in Ubuntu (10.04, Lucid), but that's not the problem here. The problem here is on the wired side. Whether I boot in Vista or Ubuntu, I cannot get it to go online. Ubuntu says that the Auto eth2 connection is established; I am able to disconnect and reconnect it normally; but I can't download updates and Firefox can't connect to CNN.com. Likewise, in Vista, diagnostics find no problem; everything seems to be fine; but no connection.
I thought the problem might be the laptop's ethernet port, so I bought a Trendnet TU2-ET100 USB-to-Ethernet adapter. It comes highly recommended; it seems to have installed successfully in Vista; it appears properly in Vista's Network Connections; its lights are blinking appropriately; and Ubuntu tells me that my Auto eth2 connection is established when I connect through that adapter. And yet still no connection to CNN.com and no downloads of updates in either OS.
I wondered if some other circuitry might be at issue, so I sent the laptop back to HP. They claim to have replaced the mobo. The symptoms remain unchanged before and after. I went through an extensive tech support call with HP. The last thing their technician could advise was to power cycle the laptop and router. The ethernet connection itself is good. I can unplug the cable from the laptop's ethernet port or the Trendnet unit, plug it into the desktop computer on which I am typing this note, and I'm connected with no problem.
I thought, well, maybe I have to have the laptop's wireless button on, even when I want to connect via wire, but that hasn't made a difference. I tried installing Windows drivers from the Trendnet website instead of from the CD; no joy. I suspect you will be as stumped as I am. I have gone through a lot of other people's comments. At this point, I am just interested in general possibilities. What, in theory, could be causing this?

I wished to use qinternet under openSUSE 11.3 to control multiple interfaces (a mixture of internet/intranet, DHCP/static IP), so I applied the same settings/tests which were successful for kinternet under open/SUSE 11.2: Selected options within Yast2/Network Settings: Traditional Method with ifupEnable Device Control for Non-root User Via QinternetYast2/System/System Services(RunLevel)/smpppd = "yes" From command line terminal:
[Code]....
Default state indicated by different icons. Interface option brought up by right-mouse-clicking on the qinternet/kinternet panel icon and choosing Settings/Various Settings/Startup tab. Note: Regardless of whether qinternet was running or not, internet communications via the relevant network interface still worked.
In case the failure of qinternet/smpppd was simply a PolicyKit issue, I edited /etc/PolicyKit/PolicyKit.conf to ensure that the relevant user had the necessary privilege to run smpppd (I assume that qinternet can be ignored since it is just the front end for smpppd) e.g.
[Code]....
This made no difference, SO FOR DIAGNOSTIC PURPOSES ONLY, I logged in as root after first removing the power from the network switches externally connected to each network interface (isolating the local host). I then ran qinternet but once again, the Interface option was greyed out. This confirmed fairly conclusively that lack of privilege was not responsible for the qinternet/smpppd problem.

Suse 11.2 > updated Feb 2 using the Update UI applet.
I had internet connectivity prior to installing the updates. Now I can't reach the internet since installing the updates. I can reach my router, log in to the router I also ping the router but I can not ping the WAN side ip on the router.
When I boot into redmond, no issues, which is what I'm using as I write this.
I have security enabled, WPA2 Personal, not that I think that is an issue as I can reach the router, my server, network printers, and PC's.
I am running a Linksys router but have replaced the standard Linksys software with DD-WRT v24-sp2 build date 12/28/09 std. One note, DD-WRT does hand out IpV6 address but I have disabled FF from using IpV6 address along with the network connection configuration applet from accepting them. (I don't remember the applets name)
In the redmond world this would be a certificate error, is this the same type of an issue? If so how do I fix it?

IPV6 gets more and more interesting. YAST is failing to connect to the repositories. I have disabled ipv6 in several ways but none of them work or YAST (also Konqueror) seems to do it's own thing. I have managed to get Firefox to work see my "slow internet seems to be down to dns post" made earlier today. So as a check on the YAST problem I loaded each of the repository addresses into Firefox and lo they all connect without any problem at all. So it seems that the YAST problem is down to IPV6
In order to disable ipv6 I initially added ipv6.disable=1 to the end of all of the bootloader APPENDS. More recently following up further info on here I added a couple of lines to
/etc/modprobe.d/99-local.conf. These were:
alias net-pf-10 off
alias ipv6 off
This doesn't work either.
Maybe of use to others - It seems it's possible to see if IPV6 is active by typing the following into the command line:
ip a | grep inet6
I'm told if it is active lines will be output? So just what do I do to disable it in YAST and I hope in Konqueror too? It's beginning to look like it is enabled or disabled at the app level according to the Firefox fix.

I'm currently using SuSE 11.4 and after running the full online updates and restarting the machine as YAST suggested, I no longer have eth0/eth1 available.
I'm clueless about what to do since I'm kinda new to Linux and at the moment, I'm trying out all the distros before making a full commitment to anyone. So far, Ubuntu has been trouble-free from day one, but I'm willing to give this distro (opensuse) some slack.

This thread (nxserver now broken?) has inspired me to install FreeNX and the client from nomachine on openSUSE-11.2 (this is the version used on both, server and client machine). The good news is: basically it works. I can connect and get the desktop. However, I have some trouble with the keyboard. Up and Down arrow keys do not work. The up arrow triggers a screen snapshot. The down arrow key does nothing. I tried to connect using qtnx as well. This does not work. Result is:
