package irqbalance 0.55+20091017-3ubuntu2 failed to install/upgrade: subprocess installed post-installation script killed by signal (Interrupt)

Binary package hint: irqbalance

Fresh install of Lucid Alpha 3.
Then did apt-get update, upgrade and got the following errors (from /var/log/apt/term.log):

Preparing to replace irqbalance 0.55+20091017-3ubuntu1 (using .../irqbalance_0.55+20091017-3ubuntu2_amd64.deb) ...

Setting up irqbalance (0.55+20091017-3ubuntu2) ...
^Cdpkg: error processing irqbalance (--configure):
 subprocess installed post-installation script killed by signal (Interrupt)

Then, after rebooting, an "installation error" pop-up was available under a red exclamation mark icon in the panel area,
which I used to generate this bug report.

Could you check wether irqbalance was running before the upgrade?

[Mathias Gug (mathiaz)]

How many cpus do you have on your system?

Could you paste the output of /proc/cpuinfo

[jimav (james-avera)]

I don't know if irqbalance was running before the upgrade, although I didn't do anything to stop it. It's running afterwards

The machine has 2 CPUs. It's a virtual machine guest configured with 2 CPUs, which I believe actually do run concurrently (the host is a quad-core i7 with hyperthreading). The VM runs under VirtualBox 3.1.4.

I'll attach /proc/cpuinfo from the guest running Lucid.

[jimav (james-avera)]

I tried un-installing and re-installing irqbalance (apt-get remove irqbalance; apt-get install irqbalance).

The problem did not recur. So it indeed may be a race condition, or possibly related to being the first update after a clean install.

Closing then.
