General :: Ubuntu Doesn't Connect After OS Update?
Jan 22, 2010
I installed Ubuntu in dual boot with Vista on my PC. First run was OK: Ubuntu started internet connection on my eth0 cable and everything worked smoothly. Then Ubuntu asked me for an update of system: after software download and reboot,th0 is not recognized anymore! I can't connect to internet, neither with Firefox neither with Synaptic.Everything is OK with Vista and internet works well from live cd (and all was ok before updating operating system). I read something around about dns problem (I have a belkin modem router) but I wasn't able to understand how to solve the problem,

I bought a Letux 400 mini netbook and it works fine except for wireless Ethernet. It finds wireless networks, including mine, and then pretends to connect, after asking for a password, but finally never connects. I tried reconfiguring the wireless network from g to b/g and finally to b only, but nothing changed. Cable connection works. Unfortunately all relevant Letux Web pages are hopelessly slow and certainly too slow to use the forum and ask questions there. why the thing doesn't connect and how to make it connect? If it recognises networks, shouldn't it be able to connect as well?

Normally Update Manager always finds the update to the next version of Ubuntu. It still hasn't given me any notion whatoever. I allready changed the settings from regular to LTS, but nothing changes. There are updates to the kernel, but I cannot download them, so I'm kinda stuck here.

I have Update Manager set to check for updates on a daily basis but to prompt me before downloading or installing them. Because I have Update Manager set to check on a Daily basis, I expect that I will receive a prompt that an update is available no later than the day after the update is available (assuming of course I have my computer turned on). Yet I only receive a prompt days or even a week after the update was made available.
For example, let's say that my PPA of Google Chrome issues an update on Tuesday. Despite the fact that my ubuntu computer was on for a couple hours in the morning on Wednesday, Thursday, and Friday, no update prompt appears alerting me to available updates. If I manually open Update Manager on Friday afternoon, then the update is there and waiting for installation. But how come I don't get an automatic prompt that an update is available? Do I have my settings wrong or something?

I'm running Ubuntu 10.04 64 bit, and my iPod doesn't seem to connect to the computer, when the iPod is connected and the computer is on before the OS loads, it says its connected, but once it starts booting, no connection. This isn't an iPod Touch or an iPhone, both of which work properly on the machine, ironically.

Just installed 10.04 on a Toshiba Portege laptop. Everything works fine except the LAN connection. Just doesn't connect. Based on what I know everything is on and enabled but no luck. The wireless works fin but can't connect to the network in my office through the standard cable. Installed the same operating system on a newer Toshiba (the second is my but the older one is a friends) and no issues at all. Wondering if it is a driver issue but can't figure it out. Am relatively new to Ubuntu but so far have found it easy to troubleshoot just reading posts and just trying out **** until it works. But this I've hit a brick wall.
Also ran in to a similar issue my work pc, except I had been working with it fine with 10.04 until I did a security update and puff... no more network. The eth1 connection is enabled and set to automatic but just can't connect to it. Sorry if I'm not providing enough info, just tell me if there is anything you need to know first and I'll post it.

Empathy used to work perfectly, it would connect to my account well. Now, for some reason, it just stays connecting with the little rolling circle thing next to the status. My account works on Pidgin though.. What could this be?

I'm having some trouble using my iPhone 3Gs with Ubuntu--specifically, Ubuntu doesn't seem to be detecting when I connect the phone at all. I don't have a password on the phone, so that shouldn't be causing the problem, and a friend of mine who also uses Ubuntu (same version) has been able to connect my phone to his computer.

System:
Ubuntu 9.04
OpenSSH 5.1p1
I recently set up SFTP on my server and in doing so wanted to create a jail for users. I went through the steps and edited the sshd_config accordingly and got everything to work perfectly. However since doing so I can no longer ssh to that machine as I once was able to do. SFTP and the jail work fine however if I comment out ChrootDirectory /home/%u and ForceCommand internal-sftp in the sshd_config; I can now ssh to that machine however the jail no longer works. I need to be able to have the jail working properly for SFTP along with being able to ssh to that machine. Is this possiblesshd_config: Jail works for SFTP but no ssh

i am wanting to use Firefox to connect to my smb shares. However, i keep getting this error message: Firefox doesn't know how to open this address, because the protocol (smb) isn't associated with any program. My client configuration is as follows: Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.9.1.8pre) Gecko/20100106 Ubuntu/9.10 (karmic) Shiretoko/3.5.8preI tried the instructions below to try and fix the problem with no success: Quote: From [URL]
Linux with Firefox In order to connect to a network share directly from you browser under Linux, you must configure Firefox to handle URL's starting with "smb://". This is done by typing "about:config" in the address line and hitting return. After that you must right-click the list of settings and choose "New -> Boolean" as shown below.
As name you must type: "network.protocol-handler.external.smb" with a value of "true". After that you must do the same thing over again, but this time choose "New -> String", type the name: "network.protocol-handler.app.smb" with a value of the path to the application you wish to use for browsing network shares. If you use KDE, this will typically be "/usr/bin/konqueror".

I wanted to test 10.04 and downloaded Wubi to do so. Normal setup, it automatically picked the 64-bit version. After booting into Wubi, installing my ATI drivers and restarting it did no longer connect to my ethernet. A few reboots didn't help so I went back to Windows for troubleshooting.
However now Windows doesn't connect to the ethernet either. It's plain dead, Windows doesn't find any connections and the modem doesn't light the Ethernet cable LED. The modem itself works fine with wireless devices. I have now tried everything including uninstalling Ubuntu, system restore, driver rollback, driver update, BIOS default settings, a different cable, a different modem etc.
This is a 64-bit specific issue because I tested the 32-bit version of Wubi 10.04 a few months ago without problems.
Windows 7 x64
Wubi 10.04 x64
Gigabyte P55-UD3 with onboard Realtek RTL8111D LAN.
I'd like to get out of this without Ubuntu effectively having broken my hardware and my trust in it.

I've just upgraded my old laptop from xubuntu to ubuntu 10.10 and I have some connectivity problems with my usb adapter Netgear WG111v3. On xubuntu I had no problems with connecting on the network but with ubuntu, it says I have good reception but it doesn't connect on the network (rarely it does, but for a very short time). I have another laptop currently running on ubuntu 10.04 and it has no problems at all (however it has an internal usb card).

I have cross posted as it is not really a wireless network problem (wireless networking works fine) but a wireless security problem (WEP and WPA security kill wireless networking).I am not total sure which forums it should be in.From original post in networking and wireless forum:I am having a heap of issues with wireless and hopefully the following will help someone out there in guru land help me fix this problem.It seems to be more then a simple computer to wireless security problem. This is long, get a cuppa and a cumfy seat and yes this did take me the better part of 1/2 a day to complete all this testing
I volunteer my various machines and time to try and fault find the issue on all machines to help the developers to fix this problem on mine and I can document everything. Hopefully this will help someone fix wireless security on Linux once and for all.

I facing a really annoying problem. I download regularly during the night using Wifi. The problem is that because I'm away, the wireless just disconnects and the pop window shows up asking me to into the password. The password is already saved in the windows so I just have to click 'connect'ut I don't understand why does it disconnect and when it tries to connect it asks for password again!y doesn't it simply 'try' to connect without asking the password when it is already saved.

I installed Ubuntu10.04 in VM. It worked without any problem. There was no GIMP in that version and thought to update the OS. I invoked update manager and updated the OS. After the update when I try to type in the password I see no response for my key board. Mouse works fine which is attached to my Key-board.
I deleted the VM completely and did a new Ubuntu10.04 installation it worked fine I could able to run couple of bash scripts but after update It doesn't response to keyboard.

I was trying to update the latest files of 10.04. During the update process suddenly my computer hanged. That was a hardware failure and my hard disk lost connection. When I solved it and boot into Ubuntu it just didn't open. A mark is shown on the above task bar that said "A problem occurred when checking for update."

The clock applet "Clock 2.30.0" in my panel reads correctly on boot, and then never updates itself. When I go to its preferences, time setting is correct and continuously updating, but the display in my panel never changes. I can use "killall-gnomepanel" from terminal, and this rests everything, making the time display correctly. Furthermore, it updates itself afterward... but I'd like the dang thing to function correctly without resorting to that.

I'm using Ubuntu 10.10. It's the only OS I have on my laptop. I hadn't updated it for over two months, and one day I started the update. I downloaded about 300 MB of updates and then started installing. While it was doing its job applying all the updates it had downloaded I had some 2 or 3 PDF files open, Amarok and a folder. Suddenly the computer crashed; mouse was dead, so was the keyboard. The computer stopped completely; I wasn't able to reboot it even with "sys rq + R + E + I + S + U + B", to give an idea. I had to kill the power to shut the PC down. But then, when I tried to turn it back on, it started booting up and then the following text showed up (shown in-between quotes):
"
Begin: Loading essential drivers ... done.
Begin: Running /scripts/init-premount ... done.
Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done.
Begin: Running /scripts/local-premount ... done.

I already tried to chroot into Ubuntu with the Ubuntu 10.10 Live CD, but when I mount the home partition and run "sudo chroot /media/Ubuntu", a message shows up that reads: "chroot: failed to run command `/bin/bash': Exec format error"
All I need is the log-on screen back on; a great deal of valuable information in the computer.

Over the past two weeks my laptop has started locking up at random. I thought maybe it was a thermal issue, because I have an upgraded hard drive (put in 2 years ago) and once a month or so I might get a heat related lockup. I keep my fans running at high speed and the laptop elevated now and don't typically have an issue.
The freezing has started to become a daily occurrence now, and yesterday it locked up three times. I am able to move my mouse (unlike thermal lockups where everything goes down) but unable to click anything. The entire display freezes, and my cpu monitor doesn't continue to update.
I finally ssh'd into my laptop and was surprised to see it responding just fine. htop showed that my X-server was at 100%. When I killed it, X restarted automatically and promped me to log in. Everything is fine after this until the next lockup.
When I don't have access to ssh I have to hard-shutoff the laptop. That can't be good on this 5 year old macbook. I have done my system updates in the past two weeks that may have triggered this, but I don't remember anything specifically. I've tried all versions of my kernel that are installed but nothing, I have the intel video and have not had problems with it up until now.
2$ uname -a
Linux macbook 2.6.32-30-generic #59-Ubuntu SMP Tue Mar 1 21:30:46 UTC 2011 x86_64 GNU/Linux
3$ lspci|grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)
Can anyone suggest something to try? I'm not sure how to go back to older versions of the the video drivers, but I'm not even sure if that is the issue. I did add the following to /etc/apt/sources.lst after the lockups started occuring:
Code:
# X
deb http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu lucid main #X-Updates PPA
deb-src http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu lucid main #X-Updates PPA
and did a full update, but this hasn't helped.
I'm running Ubuntu 10.04 LTS
