I also met the problem when I upgraded my Ubuntu10.10 (64bit)

[ceylon (ceylon)]

The problem seems to be the execution of 'start cups'... running '/etc/init.d/cups restart' while the post-installation script is hanging at least *seems* to resolve the issue here.

[Daniel Amendoeira (daniel.amendoeira)]

The first time I tried the update with 'apt-get upgrade', it hung on 'cups
stop'. I killed the process, and apt continued, complaining it did not
install everything.

I then stopped (had to kill -9) cups manually, and tried the upgrade again.
This time it hung on 'cups start'. I again killed the hung process, and apt
finished the install.

At the moment, I'm unable to start or stop cupsd, since it hangs on 'start
cups'. Since the init.d script now instructs to use start and stop
(initclt)... I'm stuck

I've just re-installed all cups related pkgs, with the same result. apt-get
hungs on 'start cups'. If I kill 'start cups', apt-get continues and reaches
the re-install job batch with success.

How can I debug why is this hanging? initctl and cupsd have no debug
options...

Issue of the upstartification of CUPS. pitti, can you have a look?

[Daniel Amendoeira (daniel.amendoeira)]

I include an strace of 'cups start', where it hangs on

poll([{fd=3, events=POLLIN}], 1, -564398304

After this, I have a process:

root 3587 1 0 22:49 ? 00:00:00 /bin/sh -e /proc/self/fd/12

which is spawning a 'sleep 0.5'.... could not make out where this one leads to.

root 4544 3587 0 22:54 ? 00:00:00 sleep 0.5
root 4547 3587 0 22:54 ? 00:00:00 sleep 0.5
root 4551 3587 0 22:54 ? 00:00:00 sleep 0.5
root 4554 3587 0 22:54 ? 00:00:00 sleep 0.5
root 4558 3587 0 22:54 ? 00:00:00 sleep 0.5
root 4561 3587 0 22:54 ? 00:00:00 sleep 0.5

If I kill the 'sh /proc...' process, the strace log unblocks, and gives out the contents of the second file (strace-start-cups-2.txt).

In the end, cupsd ir running fine, despite this nasty kill process.

I've had the same problem when updating to cups_1.4.4-6ubuntu2.2_amd64.deb. I suspect it's due to this bug: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/672438

[Daniel Amendoeira (daniel.amendoeira)]

I tried the proposed workaround in bug 672438, as pointed by ceylon, and worked like a charm.

Let's wait and see what happens on the next update.
