I was trying to execute a windows executable with wine. The terminal
output said I had a 64 bit wine installation and I needed to install
the 32 bit wine with the following command:
apt-get install wine32:i386
I was running it in the small dropdown terminal from Dolphin, so I
didn't see the whole output at once, but since this was (as I thought)
a normal operation, just installing a 32 bit version of wine alongside
the 64 bit version, I didn't think much of it and said yes. There were
no warnings besides the usual apt warnings.
Then I noticed a message pop up in the terminal talking about how
applications using phonon will remain with no sound and I just thought
that meant 32 bit applications will have no sound, so I said OK. After
that, I noticed a lot of stuff getting removed and leaving the system
in a broken state and I realized something was wrong. At the end of
it, the terminal disappeared and now many basic Plasma applications
are gone. ...
