package mysql-server-5.1 5.1.41-3ubuntu7 failed to install/upgrade: subprocess installed post-installation script killed by signal (Interrupt)

Description: Ubuntu lucid (development branch)
Release: 10.04
Failed to install mysql-server 5.1

I used synaptic to insall LAMP. When it tried to install mysql-server-5.1 it stalled (about 51%) of the installation. I had to kill (Ctrl+C) the operation, and the rest of the installation continued.

I had the same problem. In my case, it seems that the cause was that apparmor was blocking mysql. I had to run sudo aa-complain mysql before I could finish the configuration. I do not remember ever enabling aa-enforce for mysql (or for anything else, in fact).

Steps to reproduce:
  sudo aa-enforce mysql
  sudo apt-get install --reinstall mysql-server-5.1

Result: apt-get will stall at
  Preconfiguring packages ...
  (Reading database ... 339276 files and directories currently installed.)
  Preparing to replace mysql-server-5.1 5.1.41-3ubuntu7 (using .../mysql-server-5.1_5.1.41-3ubuntu7_i386.deb) ...
while trying to execute 'stop mysql' in the prerm script.

Work-around:
  sudo aa-complain mysql
  sudo apt-get install --reinstall mysql-server-5.1
gives the expected result.

How long have you waited before killing the installation?

With the latest update the problem solved.
May have been some bug in the kernel?
