[Bug 1574240] Re: package plymouth (not installed) failed to install/upgrade: conflicting packages - not installing plymouth

[Steve Langasek]

The error in your log is:

Selecting previously unselected package plymouth.
dpkg: regarding .../plymouth_0.9.2-3ubuntu13_i386.deb containing plymouth:
 plymouth conflicts with console-common
  console-common (version 0.7.88) is present and installed.

dpkg: error processing archive /var/cache/apt/archives/plymouth_0.9.2-3ubuntu13_i386.deb (--unpack):
 conflicting packages - not installing plymouth

This is correct, plymouth does conflict with console-common; this is not
an accident.

The question is, why did the package manager not remove console-common
in order to let plymouth be installed?  Later on in your
DpkgHistory.txt, we see that console-common *is* being removed.  So this
looks like a package manager bug for not correctly removing the package
earlier.

** Package changed: plymouth (Ubuntu) => apt (Ubuntu)
