It looks like the logic in the upgrader flags as an error if there are previous enabled php mods enabled in apache. It's a bit of a hack but for ubuntu I changed the logic to make it disable those other mods; for Ubuntu we always only support a single php version at a time, so this should work for us. I'm not sure this is suitable for Debian since sometimes multiple php versions are supported. However, at least this could point to where a more generalized solution could be developed.
