package lxc (not installed) failed to install/upgrade: subprocess installed post-removal script returned error exit status 1

[Austin S. Hemmelgarn]

=====================================
SRU Justification:
1. Impact: 'apt-get purge lxc' fails
2. Development fix: accept 'purge' as a valid argument to the postrm script
3. Stable fix: same as development fix.
4. Test case:
   sudo apt-get install lxc
   sudo apt-get purge lxc
5. Regression potential: this accepts 'purge', which is a valid option, as an argument to the postrm script. If there were a regression it would only be seen at package uninstall.
=====================================

Occured while trying to purge all installed lxc packages.

Thanks for submitting this bug, the postrm script does indeed have a bug which is present in precise but not quantal. I"ll therefore mark this fix released and request SRU for the postrm fix for precise.
