There is a serious bug when using apt-get autoremove in freya 0.31. E.g. when installing or removing packages, apt-get will indicate packages that are no longer used and suggests to remove them with autoremove.
However, if you then use that command, apt-get will remove also packages that are still in use. When I noticed it, apt-get tried to remove Brasero. My terminal in that case looked like this:
"Die folgenden Pakete wurden automatisch installiert und werden nicht mehr benötigt:
ksh libgssdp-1.0-3 libgupnp-1.0-4 libpantheon-files-core0
libpantheon-files-widgets0 libunique-3.0-0
Verwenden Sie »apt-get autoremove«, um sie zu entfernen." (= the following packages aren't used anymore....use "apt-get autoremove" to remove them)
When using autoremove, the packages to be removed read like this:
"Die folgenden Pakete werden ENTFERNT: (= the following packages will be removed)
brasero brasero-cdrkit brasero-common dvd+rw-tools growisofs ksh
libbrasero-media3-1 libburn4 libexempi3 libgail-3-0 libgssdp-1.0-3
libgupnp-1.0-4 libisofs6 libjte1 libpantheon-files-core0
libpantheon-files-widgets0 libtotem-plparser18 libunique-3.0-0
libzeitgeist-1.0-1 session-migration"
Does anyone have a hint how to solve this? It seems to be a quite dangerous bug to me, as it could potentially damage your system if you're not attentive enough.
