Ubuntu :: 11.04 Upgrade - Internet Access Broken
Jun 12, 2011
11.04 has finally fixed my Screen Resolution problems. Yippee. But now the Internet access has broken, again rendering my Ubuntu installation mostly useless. Yes, it tells me Wired internet disconnected, after repeated attempts to gain access to the internet over a LAN cable. I have tried everything to get it to work, even manually entering all the info to allow access to my router. But still No. What is even more frustrating is that the internet worked fine on the Live CD, but not on the final installation.

I just did a large patch on my opensuse11.3 system (upgrade of all installed packages), and whilst my network interface works, I cannot get past my router onto the internet.
I can connect to other computers on my network (here at home), I have an IP address via dhcp from my router, but I cannot get internet access, either from thunderbird, firefox, or simply by [URL] Clearly the computer was connected to the internet just fine minutes before since I did the large patch! Also, my other computers CAN still connect to the internet.
how i can debug it? It is just too coincidental I have upgraded everything and now somethings amiss!
If it's relevant, my router is a netgear WGR614v9.
A few things I've tried...
Code:
linuxthinkpad:/var/log # /sbin/route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth1
link-local * 255.255.0.0 U 0 0 0 eth1
loopback * 255.0.0.0 U 0 0 0 lo
[Code]....

After my "upgrade" to 10.04 I am unable to access the internet at home with wireless using Firefox, but am able to access the router. I am however able to access the internet at work, both use WPA password protection. I was also able to do the updates over wireless at home, despite not being able to access the internet. I am currently at work, and downloaded Google Chrome and did not import settings from Firefox, to see if there were any settings issues with Firefox itself.

I just upgraded from Suse 10.x to 11.2. Unfortunately, I didn't use 10.2 much and I('m a bit overwhelmed by the upgrade. Any advise is greatly appreciated.
After my upgrade, I lost Internet access. I don't really know my way around too well, but I did try to ping my router, but had no success. (Although I can ping 127.0.0.1).
I'm guessing that this means network access is not configured, although it looks OK to me.

I have a linux box (fedora) with two ethernet cards eth1 and eth2. On eth1 I successfully configured a PPPOE internet connection. Such that from the server I can browse the internet. On eth2 I wired it to a wireless router essentially to provide the wireless cloud. On eth2 I also configured dhcp, such that the Linux box is both PPPOE and DHCP server.However my clients on the LAN cannot access the Internet.
On passing the routing command I get
Destination Gateway Iface
196.44.x.y 0.0.0.0 ppp0
192.168.1.0 0.0.0.0 eth2 (my subnet)
0.0.0.0 0.0.0.0 ppp0.
The router (functioning as a wireless access point mainly) has a fixed IP address of 192.168.1.2 and eth2 has IP address 192.168.1.1. The dhcp file running on Linux has been set with option router (Gateway) 192.168.1.1. I cannot figure out how to correctly set the routing table such that my clients on wireless can access the internet cloud. I googled and googled but no solid solution. Any suggestions?

I was having a problem with a fresh 11.04 install and the VPN software I use for work. I found the fix was to upgrade the software, so I downloaded an RPM, converted it to .deb and installed it via dpkg. The install worked and the VPN software now works, but Package Manager says I have a broken package and wants to 'upgrade' to the older broken one. How can I fix this without breaking my VPN SW again?

I managed to configure my W890i phone to get access to internet through an ubuntu-based computer. It's very easy to use the phone to give internet access to the computer, but the opposite is quite more tricky. For that I've done the following
----On the phone---
-Set the USB network option to "through computer", so that the phone uses the computer's internet connection and not the opposite.
-Decide and set "Shared Network" parameters: user, pasword and workgroup.
-In "conectivity-> internet connection" set "allow local network" to "yes"
----On Ubuntu 10.04---
-Install samba, samba-client, smbfs, smbclient, firestarter and dhcp3-server
-Configure Samba (System-> Administration-> Shared folders): same workgroup as in the phone, add new user (the phone), passwd this new user. In my case the user was called "w890i" and the password given was the same.
-Once the phone is connected to the computer through USB (then select "phone mode"), a new connection appears in NetworkManager: usb0.The aim is to create a shared network that gives internet access to this device. Edit the IPv4 parameters of this new connection, set them to Manual and give an IP adress (192.168.0.1) and a subnet mask (255.255.255.0); the rest of the fields are left empty.Connect this network.
-Set firestarter to use dhcp3: sudo ln -sf /etc/init.d/dhcp3-server /etc/init.d/dhcpd
-Launch firestarter and follow the wizard. Set "allow internet shared connection", choose the device for the primary internet access, and then the device for the shared network (usb0). Then change the settings for firestarter: activate DHCP for local network, set IP to the one we gave before (192.168.0.1).
-Open dhcp3-server config file sudo gedit /etc/default/dhcp3-server And set INTERFACES="usb0"
-Set the policies of firestarter: in incoming connections, allow connections from the IP adress given to the phone (192.168.0.1). Then add rules for the ports that need to be open for this connection. I opened HTTP, HTTPS, SMB, SMTP, POP3, IMAP, IMAPS, DHCP for all the connections in the local network.
-Apply policies and start the firewall.
------------
After all this, the phone can access the internet through the computer. Two problems appeared:
1. I couldn't get access to https sites, like webmails. The phone gave a "communication error". But then I tried with Opera instead of the browser built in the phone's firmware, and I could finally get to https sites.
2. I couldn't retrieve mail, neither POP nor IMAP nor IMAPS. I thought it was a firmware problem again, and I tried out several mobile phone email clients written in java, but none of them worked.
So this is at the moment the problem. If I connect from the phone to the internet directly through 3G, the email clients work for all my accounts. I don't think it's a firewall problem, because the ports are opened for this connection

I forgot that Python is actually essential to Gnome and wanted to update to 3.1, and didn't realize my mistake until some of Gnome had been removed, then I Ctrl+C'd out. Now I can't even connect to the internet to repair my broken packages. I'm out of town for Mother's Day, but in the car it occured to me that I should have tried my Live CD.
As a side issue, is it alright to install more than one version of Python? I'm guessing so, so long as I keep track of which one I'm calling. I used apt-cdrom to update my sources.list appropriately so I could apt-get from the Live CD, but apt complained about locales. Now sources.list has strangely lost the cdrom line, but I'll put it back when I next boot to repair mode.

internet access is no longer working on my computer, ie wget, ping, apt-get update all return unkown host (url or whatever).
However the system monitor (Network History) shows that the system is sending and receiving packets. And what I think is network manager applet shows active network signals for both wireless and ethernet.
I know my laptop has not acquired hardware faults. Since I am posting this message and accessing the internet through the same computer with a Ubuntu live USB start up disk.
I searched through the forums for related posts and tried suggestions. Forinstance
the /etc/resolv.conf
file is the same for both live usb system and hard drive system, so it can not be that.
# Generated by NetworkManager
nameserver 79.138.0.180
nameserver 85.8.31.209
the /etc/network
interfaces file looks like:
code....
I tried the system test (System->Administration->System Test), with only Network tests selected). The results of system test were so extensive I searched for the word internet and extracted lines for internet. Interestingly it says both the network_test and the internet_test are _passed_.
But the internet does not work in either in web browsers or with BASH commands.
And also:
erlang-inets Erlang/OTP Internet clients and servers
python-twisted-bin Event-based framework for internet applications
python-twisted-core Event-based framework for internet applications
network_test pass
internet_test pass

After upgrading my 64bit 9.10 install to lucid, KDE went poof. I am presented with the login screen, and after supplying my credentials the screen goes black and all I am left with is a mouse pointer.
According to ps kded4 is dead (zombie). kdm.log also indicates a problem with ibus. I installed the "ibus" pkg, but didn't resolve it. Attached is an excerpt of my kdm.log, I can't really find useful information in syslog/dmesg/messages. The system is up-to-date and I've tried starting with a clean user account as well as removing the .kde directory.

Curious thing happening since upgrade. The desktop toolbar is invisible, although I can get click and access the drop down menus for login, calander, power settings etc. Alt-tab works in 2D. The new desktop icons for natty are also invisible. I have tied to access a terminal using Alt-F2, but terminal window doesnt open. I had compiz running on previous 10.10 installation. I am at a loss as to where to begin fixing this. If I didn't have a windows 7 installation partition that would get screwed up I would flatten the installation and download and install a fresh install, but I do and I don't want to go through that pain if I don't have to.
Running Lenovo 3000 C200 with intel gm1345 gfx.

Like so many others, after upgrading 8.04->10.04 LTS, Bluetooth is now busted. I've spent the better part of a day trying to find answers; I've tried many things and the results have not been consistent. I'm not going to write a book here as there are many other posts on the same problem and no real answers other than to complete a fresh install. I CAN do that but I'll have to overcome one bothersome problem:
Bluetooth is an important protocol. Now my (Bluetooth) broadband adapter is busted and I have to try and resolve this issue using a lousy phone line and modem. Needless to say... I can't download a new distro with that configuration. The updates would take weeks!
I suppose I'll have to drive into town and get someone to burn me a copy of 10.04 lts... Hope that works!
I'll think twice (or more) before upgrading an LTS distro again! That machine was working great....I don't know why I upgraded.. security concerns mainly. live and learn I guess... live and learn.

I was updating from 10.04 to 10.10 (was updating through update manager) after some time I got following message:
Code:
An unresolvable problem occurred while calculating the upgrade:

Came across a broken link during updating system (Python). So I came across advise which I followed and though I had fixed the problem by removing the broken (python) Only to find I no longer have access to the Desktop.
This is what I have done so far:
Booted to Recovery
Logged in as the user.
Ran the following to reinstall desktop:-
sudo apt-get install ubuntu-desktop
All seem well, but now it wants conf. So I have ran the following after rebooting:
sudo dpkg --configure -a
But still no joy, as when the system reboots it stops at the splash screen desktop ubuntu and seem to be trying to boot to the desktop. But no joy.

I installed 11.3amd64 as a VM under Vista/VMWare Player - all worked fine. I have now installed it as a physical system. It nstalled cleanly BUT during first boot it could not access the repos. With each repo it gave the message
- download (curl) error for (repo)
- error code connection failed
- error message could not resolve host (repo)
This was followed by a message box containing
- UI syntax error
- no widget with ID 'contents
Firefox could not access the internet (cannot find server) until I disabled IPV6 (I used about:config), now it works fine. I think the repos problem is because of IPV6 - I usually have trouble with IPV6. I tried disabling IPV6 with the following (How To Disable ipv6 on SuSE Linux | Linux Poison)

I have an old FC2 box running Squid version 2.5. It has been running since 2003 so I am in the process of replacing it. I have a new machine with FC11, iptables, and Squid 3.0 installed.
On the old machine I use iptables to intercept Port 80 traffic and send it to Squid. By default I block all internet access and allow only sites that are in an Allowed_Sites.txt file. Within Squid I also have statements to allow certain users to bypass Squid based on their IP address.
I have set up the same thing on the new box. I have iptables intercepting the Port 80 traffic and sending it to Squid. That is working because if I remove the redirect statement from iptables all internet access is blocked.
The problem I am having is that Squid is not blocking any websites. It acts like the ACL is set to http_access allow all. I have worked on this for several hours and am stumped.
These are my Squid rules:
acl allowed_sites url_regex "/etc/squid/Allowed_Sites.txt"
acl manager proto cache_object
acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32
acl SSL_ports port 443
acl CONNECT method CONNECT
http_access allow manager localhost
http_access deny manager
http_access allow Bypass_Users
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports

Today I installed all the updates that were associated with the 2.6.31-17 kernel upgrade on Ubuntu 9.10.It appears the update has broken my stock 17-inch Macbook Pro 5,2 because after restarting my screen is just black. I don't see the ReFit choice menu (I have OS X and Ubuntu installed), and even when I let the machine boot all the way into Mac OS X the screen just remains black. The apple logo on the back of the screen doesn't turn on at all.
I can see the keyboard backlights eventually come on (which is normal when you get to Mac OS X login prompt) - so its almost as if its booting but just wont talk to the display. When you press the brightness buttons you can faintly see the shade of black changing.What the heck has happened? I just paid a big load of money for this baby and I'm very sad now I love Ubuntu but this is ridiculous.

I started an upgrade last night (from Jaunty to Karmic) using a "do-release-upgrade" command on a remote server via ssh. However, this morning, I discovered that the ssh connection between my machine and my server was broken.
I can see that the do-release-upgrade process is still running (well, a giant /usr/bin/dpkg is in the process list) and waiting for a response.
Is there any way I can take control of that session from my current session?

I've only been using Linux for a few days (Specifically - I installed Ubuntu 9.10 last week on my laptop for learning the OS and updated to 10.04 over the weekend). I have searched Google (and found answers) for every problem now except for this new one. I apologise in advance for the length but I wanted to include my own troubleshooting as well.
When I installed and setup Ubuntu Karmic - I added my work software. Autopackage wasn't installed by default so I used terminal's package install <filename> command for the first file - and double clicked on the rest to install.With the OS change I wanted to check to see if these packages would have problems installing on 10.04 (mostly to double check).First I checked my Manage 3rd Party Software to remove them - but all my entries here are blank. (I should have quite a few actually - I've done a lot of installing and downloading in the last few days).I double clicked to re-run them but that failed saying there was a problem with the packages. So I swapped to Terminal and found the following:
When I try to install a software package:
sudo package install "SMART Product Drivers 10.package"
Reply: package: can't open config file /home/test/.mailagent
If I type in just
[code].....
What's interesting, is checking my Fedora and Debian builds (I've done a lot of learning for only a few days! But I know a ton about grub 1 and 2 now) - I can't see a /home/test/.mailagent file or folder to copy either. The only thing I can think of is I have never setup an email account on my system (I've only been using it for a few days) and maybe the blank Manage 3rd Party Software tab is indicating a different problem.

I recently upgraded Ubuntu 9.10 to 10.04 and my wireless stopped working. It can detect that there are networks around, what their signal strength is, and then try to connect to one, but it just keeps connecting. After around 5 minutes, this stops and nm-applet says no network connection.
After I try to connect, dmesg is spammed with hundreds of the same message. I can not post these here, as I am writing from a different computer and I have no internet access from my main computer.Also, there is nothing in interfaces.conf other than lo. For some reason, my card is referred to as both wlan0 and wmaster0, with this changing depending upon where I look.Most interesting of all is that, even after I reinstalled 9.10, wireless is still broken, even though it wasn't before. It also used to work under liveCD.

Anyone have an idea here? I have searched a lot and have only found a few references to this issue. Does the invalid flag message relate here? The partition is flagged as 'boot'.
