Bug#621720: if I attempt to remove apache2.2-common apt wants to install apache2-mpm-prefork

[Faheem Mitha <faheem@email.unc.edu>]

Package: apache2.2-common
Version: 2.2.16-6+squeeze1
Severity: normal


I don't know if this is an apt bug. I thought it might be a packaging
issue. If it is an apt bug, please reassign it. Thanks.

I have the following apache related packages newly installed by doing

orwell:/home/faheem# sudo apt-get install apache2
