The error in the logs is:

 Unpacking replacement nfs-common ...

Everything looks like it's going according to plan, and then the directory isn't empty. Can you please show the output of the command ' ls -l /var/lib/nfs/rpc_pipefs' on this system?

[Steve Langasek (vorlon)]

ok. can you please also show the output of these commands:

mount | grep pipefs
fuser -vm /var/lib/nfs/rpc_pipefs

You may have to install the psmisc package for the second command to work.

Ah, that's not what I expected to see. Have you rebooted since you
originally filed this bug?

Can you show ls -l /var/lib/nfs/rpc_pipefs/nfs?

[Valon (darkelfshao)]

I didn't really think about it and had shutdown since filing the bug report. Whoops!

[Steve Langasek (vorlon)]

Ok, unfortunately that means there's nothing else we can do here to diagnose. You should be able to upgrade nfs-common now without problems.

[Valon (darkelfshao)]

It happened again today during another update. I have not restarted the machine.

Ok. I don't know what created this directory, then; you should run 'sudo
rmdir /var/lib/nfs/rpc_pipefs/nfs', then the upgrade should complete.

Do you have nfs-kernel-server installed on this machine?

nfs-kernel-server is not installed.

The update worked now.

Thanks.

Huh. Looks like something that predates rpc_pipefs.

Ok, will switch this to an rm -rf. Thanks for the analysis, Chad.

[Launchpad Janitor (janitor)]

This bug was fixed in the package nfs-utils - 1:1.2.5-3ubuntu3

---------------
nfs-utils (1:1.2.5-3ubuntu3) precise; urgency=low

  * In some cases, /var/lib/nfs/rpc_pipefs is successfully unmounted on
    upgrade but the directory still has contents within it. Since this is
    /var/lib we shouldn't assume it's ok for delete these; instead, pass
    --ignore-fail-on-non-empty to rmdir. LP: #954619.
