Public bug reported:
Binary package hint: apt
today I was trying to remove plymouth to solve a black screen during
boot issue, and apt got me some pretty odd messages... first was about
an Apache engine (apache2-mpm-prefork) being incompatible with another
(apache2-mpm-worker)
Of course they are, but why removing plymouth woukd trigger this?
So I have tried to install the latter (apache-mpm-worker) which, of
course removed the incompatible one automatically (apache-mpm-prefork)
and a few php5 libraries with it...
$ sudo apt-get remove --purge plymouth

procps : Depends: upstart-job
Depends: initscripts but it is not going to be installed
E: Broken packages
when I have tried it again I got this even stranger message about
upstart-job and iniscripts ... but none should be affected or envolved
with the plymouth package I was trying to remove.
$ sudo apt-get autoremove --purge plymouth

I am not installing or removing anything that could trigger that
messages! Not sure what could happen if keep walking dows this path, but
it seems that it will destroy my machine, so I gave up and reinstalled
the packages I have taken out just in case
is my packaging system broken beyond repair?
