CFS error blocks dist upgrade to 7.10

[uranium]

Binary package hint: update-manager

I was trying to dist-upgrade to 7.10 via the update manager. I'd just updated to 7.04 the previous day.

In the "installing the upgrades" phase, it stuck on handling CFS. I don't know why, but cfs.postinst just seemed to sit there indefinitely, making no progress and giving no output. After 5-10 minutes of waiting for it, I just killed it and let the update continue. It later stuck on exim, with 3 processes of exim4-base.post running, apparently doing nothing. I killed them, and the installation continued. Later in the update, I got this in the update window:

Setting up scim-modules-table (0.5.7-1ubuntu2) ...

Errors were encountered while processing:

gutsy: Fatal IO error 9 (Bad file descriptor) on X server :0.0.
Setting up cfs (1.4.1-18) ...

I then got an error popup about CFS, and the overall update claimed to have failed, and that it was going to do some cleanup to make sure I wasn't in an invalid state. However, so far [10 minutes?], I've seen no further output or activity, so it looks like it's hung.

Thanks for your bugreport.

Here is what causes the error:
....
Setting up cfs (1.4.1-18) ...
dpkg: error processing cfs (--configure):
 subprocess post-installation script killed by signal (Terminated)
...

I reassign.

Thanks for the logs.

I reassign to cfs, it looks like it is not using debconf for prompting.

Did you see a terminal window open during the upgrade asking you questions about some stuff in /etc/exports?

[uranium (uranium+ubuntu)]

Hmm; this was a while ago now, so I can't be absolutely sure, but I'm pretty confident that there was no popup. It just hung without any notification. /etc/exports rings a faint bell, but I did 3 dist-upgrades in the space of 2 days, so that may not mean much [I've now gone from 6.06 to 8.04].
