Lost networking Ubuntu 11.10

I've upgraded my Linode to Ubuntu 11.10 per the guide and now all networking is lost. I can connect to it via Lish, but nothing else. No Apache, no SSH, no nothing. What did I do wrong? Is there something in Ubuntu 11.10 that is causing an issue with Linode? Any help would be great.

Upgraded from which version?

You followed the guide in the Linode Library, or the Ubuntu upgrade guide?

Have you watched the Lish console during a reboot to look for errors?

Chances are the console will show you something, and that would be the place to start…

What does your /etc/network/interfaces look like? How about the output of "ip addr", "ip route", and "ip -6 route"?

I would have had the same problem on 3 Ubuntu machines (two x32 and one x64), if I did not first see:

That is, I noticed the problem on on x32 pc and then fixes the problem, and followed the simple instructions for the other two machines.

Regrettably, unless you can get into your machine from LISH or something like that, this may not help.


mkdir /run /run/lock

rm -rf /var/run /var/lock

ln -s /run /var

ln -s /run/lock /var


On my Linode, I just tar'd /var/run and /var/lock, untar'd them in /run and /run/lock, and after the reboot I did the rm's and ln's.


On my Linode, I did the above in addition to following the new instructions for 11.04 -> 11.10 on
