Plesk Autoupdate Broke Apache

[AndyD]

I ran autoupdate from the Plesk panel which ended with:

Errors were encountered while processing:
/var/cache/apt/archives/python_2.4.4-2_all.deb
/var/cache/apt/archives/python-minimal_2.4.4-2_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
ERROR: An error occurred on attempt to install packages.
Attention! Your software might be inoperable.

And left nothing working. I managed to get Python installed by manually removing it and then installing it again.

Apache stayed broken and I couldn't run the autoinstaller again to fix it. So I thought if I remove psa and then install it again that will reconfigure Apache.

So I ran:

dpkg -r --force-all psa
apt-get -f install

Which kind of worked, but now the sites only working in IE. If you try to open a site in Firefox it wants you to download the file instead of displaying it. And the server just generally feels different.

Is there any way I can easily force Plesk to reinstall without losing my configs?
