Followup-For: Bug #985297
Control: tag -1 patch
Hi Rene,
I've been experimenting a lot to fix this bug.
One problem is Breaks in one package being handled first (by
deconfiguratio) and subsequent occurrences of Conflicts in another
package will be ignored for deconfigured packages (and removal will not
happen).
We can fix most of the upgrade issues by propagating the Conflicts to
the package with the Breaks, s.t. deconfiguration does not happen but
removal does happen immediately. Unfortunately this does not work if
there are too many packages the would need to be removed together since
dpkg does not get the optimal ordering for doing that. These are mostly
upgrade paths with libreoffice-impress or libreoffice-report-builder
installed.
So in the end I resorted to not using
dpkg-maintscript-helper dir_to_symlink
as I had initially suggested but fixing it up manually in the postinst.
I've running various buster->bullseye upgrade scenarios (with and
without recommends, direct distupgrade vs upgrade && dist-upgrade)
with the patched packages as upgrade targets. I've rerun all piuparts
tests that had libreoffice-common installed and haven't seen any more
problems with the patched packages.
The attached patch does only patch debian/control.in, please regenerate
debian/control as this caused a lot of noise (I did nocheck builds).
It also contains adding some weird symbols with symbol version GLIBCXX_3.4
that looks weird, because libreoffice should not provide symbols with
such a version. This could also be an artefact of how I did build the
packages. Please decide what should happen to them.
Andreas
