ubuntu 10.04.2 LTS hangs after dist-upgrade ( i get some apt errors )

Asked by Venugopal

Hi,

we have a ubuntu 10.04.2 LTS box which needs patch & security updates. Initiated apt-get update & apt-get -V upgrade, there was an error regarding x11-common package. Otherwise upgrade reported no more errors. But the machine hangs during reboot at the network-setup stage.

Can someone provide pointers on this.

Regards,
Venugopal

Hi, I tried with the command, it gives the same error while processing x11-package.

 x11 isnt important for server, so I just moved the template file & got rid of this error. But the server still hangs upon reboot and below is the message on console & it hangs for ever.

apt-get update gave some errors, could this be the actual problem?

sudo apt-get update

I believe that Debian repo can make you trouble.It will be better if you can find somewhere else packages you are receiving from that repo.

Hi, You are right. The debian backports repo caused the issue by pulling initramfs-tools package. Somehow unvalidated package initramfs-tools (0.92bubuntu78 => 0.99~bpo60+1) was selected by default & it broke the system. After reverting this to old version, machine is working fine.

Thanks to all who helped.
