I tried to compile a 32bit program and had a conflict when trying to install some the dependencies, namely libssl-dev:i386 and liblz02-dev:i386. The only way to fix that mess that I could figure out was sudo dpkg -r --force-depends which seemed to work.
A while later I wanted to update and apt-get listed a whole load of packages that were supposedly not needed anymore. I really didn't pay enough attention here and ran sudo apt-get autoremove. I mostly managed to fix this after I noticed that I needed and manually installed a whole bunch of them but manage to reinstall them by grabbing the packages out of the shell history.
Except that steam didn't want to install anymore:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
steam:i386 : Depends: libgl1-mesa-dri:i386 but it is not going to be installed
Depends: libgl1-mesa-glx:i386 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I have tried pretty much everything that I could think of or find.but I am really not sure what the actual problem is.
