Public bug reported:
The HPLIP installer, in automatic mode, removes existing hplip and hpijs
packages. As a side effect, the installer also removed lots of
unrelated, but important packages. This could seriously damage the
entire Linux installation !
Explanation of the error: In Ubuntu 8.04, packages hplip and hpijs are
installed as dependencies under an important parent package, called
'ubuntu-desktop'. Although these dependencies don't have priority
'depends' but only 'recommends', the use of flag '--assume-yes' seems to
trigger the removal of the parent package 'ubuntu-desktop'.
In a cascade-like fashion, dozens of other packages that are
dependencies of the parent package are also removed. This includes
packages like: Xorg, brasero, tomboy, f-spot, compiz, network-manager,
tracker, mono-runtime, pulseaudio and lots of library and support
packages related to these packages.
The HPLIP installer gives absolutely NO on-screen indication that all
those packages are removed. I only found out what was going on when I
manually checked the package install log file to see why the removal of
two packages (hplip and hpijs) was taking so long...
Shocked, I immediately interrupted the HPLIP installer and have tried to
reinstall all removed packages. It looks like I was quick enough, and
don't have to restore a backup.
Side question: IMHO, the Ubuntu install utility reacts in an unexpected
manner on the removal of two non-mandatory dependencies. Strictly, this
is not only the responsibility of the HPLIP team, but also of the Ubuntu
team. Can I try to link this bug report to their project as well, or
should I enter a separate bug report?
