Hi,

during a "zypper --releasever=15.6 dup" upgrade from a fully up-to-date 15.5
installation I got the following messages:

Checking for file conflicts:
...................................................................................................................................................................[error]
Detected 4 file conflicts:

File conflicts happen when two packages attempt to install files with the same
name but different contents. If you continue, conflicting files will be
replaced losing the previous content.
Continue? [yes/no] (no): yes

Even though this is mostly harmless, it disturbs the upgrade experience and
probably can be easily fixed by backporting the clang-cpp/update-alternatives
change from clang17 to the other clang versions that are part of Leap.
