Re: aptitude dist-upgrade removes important packages

Florian Kulzer wrote:
Most likely it is not a bug. It seems that some packages have been
marked as "automatically installed" and no other package on your system
depends on them anymore. In that case aptitude will remove these
"unused" packages unless you change that configuration option.

This should be fixable by running

aptitude unmarkauto '~M!~R~i'

to remove the "auto" mark from all the packages on which no other
installed package depends
These packages are marked as auto, but I am not sure if your fix will do what you think

root@main:~# aptitude unmarkauto '~M!~R~i'
