Comment 1 for bug 969426

Hi Ben

Looks like you might have two issue here:

1) apache2-mpm-prefork gets removed which libapache2-mod-php5 depends on:

The following packages will be REMOVED:
      apache2-mpm-prefork libapache2-mod-php5

This is because you are running 'apt-get -y install apache2' rather than actually upgrading so apt selects the default worker type - you should run:

  sudo apt-get dist-upgrade
or
  sudo apt-get update

2) Apache not restarting correctly

Might be caused by the above - please try and see if it still happens.

Otherwise any errors from the apache log files would be good to see.

Marking 'Incomplete' and 'Low' for the time being as I don't think this is a more general issue.
