Bug#1036580: llvm-defaults: plese add some Breaks for smoother upgrades from bullseye

[Andreas Beckmann]

Source: llvm-defaults
Version: 0.55.6
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts

Hi,

while analyzing piuparts bullseye->bookworm upgrade logs I found several
of your packages not being upgraded but held at the bullseye version.
This is usually caused by apt having a hard time removing an obsolete
package in order to install its (differently named) successor, if there
is only a transitive conflict between them.
These upgrade paths can be improved by adding some Breaks to higher
scoring packages.

Please consider applying the attached patch.


cheers,

Andreas
