Ok, thanks, good to know.

I use "aptitude" in its text-mode "GUI" version. Just "aptitude" as
root, then "u" to update the packages list, then "g" to start to update
the packages.

Lately it was always 3.8+dfsg1-${N-1}, and before that it was
3.6+dfsg1-4, according to:

  # zgrep -h lazarus-ide /var/log/aptitude* | sort

See attachment. This is from 3.8+dfsg1-7. --> No, it is now from
3.8+dfsg-8, which I installed during writing this EMail, see below. But
from a visual check it looks very similar if not identical.

Yea, as said, it complains a lot about files which it overwrites, but
it finishes, and then dpkg as well as aptitude are happy, i.e., there
is no unconfigured package or something like that.

Interesting! After i purged all lazarus-*-3.8 packages, I still had
many 3.6 packages left.

Entfernen von lcl-3.6:amd64 (3.6+dfsg1-4) ...
Entfernen von lcl-units-3.6 (3.6+dfsg1-4) ...
Entfernen von lcl-gtk2-3.6 (3.6+dfsg1-4) ...

Entfernen von fpc-3.2.2 (3.2.2+dfsg-45) ...

Entfernen von lazarus-ide-3.6 (3.6+dfsg1-4) ...
Entfernen von lazarus-src-3.6 (3.6+dfsg1-4) ...

Then I've installed a fresh lazarus with all dependencies, plus FPC,
and there where no such errors any more. There are no unconfigured
packages and aptitude is happy. I hope I didn't have any custom Lazarus
or FPC configuration files. :-)

However, I got a few warnings:

update-alternatives: Warnung: Erstellung von
/usr/share/man/man1/lazbuild.1.gz wird übersprungen, weil die
zugehörige Datei /usr/share/man/man1/lazbuild-3.8.1.gz (der Link-Gruppe

update-alternatives: Warnung: Erstellung von

This says in German "Warning: Creation of ... is skipped, because the
file ... (of the link group lazarus) doesn't exist." for these 5 files.
They also don't exist after the installation:

# stat /usr/share/man/man1/lazbuild.1.gz
/usr/share/man/man1/lazre.1.gzs /usr/share/man/man1/lrstolfm.1.gz
/usr/share/man/man1/svn2revisioninc.1.gz
/usr/share/man/man1/updatepofiles.1.gz 
stat: cannot statx '/usr/share/man/man1/lazbuild.1.gz': No such file or
directory
stat: cannot statx '/usr/share/man/man1/lazre.1.gzs': No such file or

Thanks for helping!
