Comment 19 for bug 290024

Hello Lars,

I was updating on Jaunty today and found 2 packages in Cruft Remover
which are in "local or obsolete" within Synaptic (doc-base and
libgnomevfs2-common). These packages cannot be removed. On the other
hand are there linux-image packages in "local or obsolete" which are
not listed in cruft remover. I have added a screenshot an will try to
figure out what the difference is between the listed packages.

> + SUMMARY FOR SRU: A subset of users can render their systems unusable, by
> + accidentally removing some packages needed for the system to work or, in
> + some cases, all or most packages. This has been handled by checking that
> + two essential packages (dash and gzip) are available in the Packages
> + files, according to apt, and aborting if not. The regression risk for
> + this change is that users might not be able to use the tool at all if
> + the new test is too aggressive, but since update-manager uses the same
> + heuristic, it should work very well.

> TEST CASE: Install without network access ("kvm -net none" suffices).
> After installation, install system-cleaner, and verify that "sudo
> system-cleaner find" finds a lot of cruft (at least several tens and
> possibly hundreds of packages). Install fixed system-cleaner (enabling
> networking is fine, as long as nothing runs "apt-get update"), and
> verify that "sudo system-cleaner find" returns nothing.
