After typing 'g' (to "perform all pending installations, removals,
and upgrades") and putting the cursor over the

id  lsb-base         -50.2 kB  11.2                     11.2

line (in order to learn why this package is removed). This is what
the bottom part of the window shows.

OK, so the real reason should be given.

Normally conflicts produce an error on packages that must not be
removed. Here, I suppose that this is OK because of

Provides: lsb-base (= 11.1.0)

(by default, this is not shown by aptitude in the package description).

Well, the "because of dependency errors" in the above message is
incorrect and very confusing. Since there are no dependency errors,
this cannot be because of dependency errors.
