Ubuntu: Ubuntu Distribution Upgrade to 12.04 freezes on configuring lswh



Question:

For the last few hours, my upgrade window to 12.04 has been stalled at configuring lswh. The top of the terminal window says

irqbalance start/running

There's a fairly long line of errors in the terminal like

error cannot seek /dev/sdc,

most of them coming after the "Generating grub.cfg". A the very bottom of the terminal it says Found Ubuntu 8.04.2 on /dev/sdb3 and then "done" on the final line.

Reading other threads on freezes during upgrade1 gives me some hope I can open another terminal window and fix this and continue with the upgrade, but I haven't found what that command might be. I found some leads here where lshw hangs:

  • bugs.launchpad.net/ubuntu/+source/lshw/+bug/218864

But the solution assumes I can just run a patch, which I can't don in the middle of an upgrade.

These two issues:

seem to suggestion killing or disabling the os-prober, but I'm not sure if I can do that mid-upgrade.

Any suggestions for fixing this?


Solution:1

CTRL-C the upgrade, do whatever you want to do, then dpkg --configure -a to restart it.
