PK simply selects the highest available version for individual packages. This makes it fail in your scenario. 'zypper up' issues only one job: 'update all packages'. This leaves it to the resolver to select the matching packages and the resolver sees the conflict, thus is able to avoid it. ---- After a glimpse at the zypp-backend code I see the backend_get_updates_thread calling zypp_get_updates which calls zypp_get_package_updates which finally calls getZYpp()->resolver()->doUpdate(). This call issues a 'update all packages' job, which is also visible in the logs. PK even sees the correct libvlc5;2.1.5-114.3;x86_64;VideoLAN as result of this call:

But it looks like only the name 'libvlc5' survives and finally leads to selection of the highest available 'libvlc5'

JFYI: All the information from comments 5,6,8 is included in a solver testcase. A testcase is not tied to a specific job, but it contains all repos, packages, patches, patterns, dependencies, hardware, locks,... and other settings which are relevant for dependency resolution. So with a testcase you can mimic almost any job or query. -- You are receiving this mail because: You are on the CC list for the bug.

zypp: only allow to update candidates (fdo#61231)
For non-patches the - in this case correctly determined sat::Solvable - is converted into the corresponding ui::Selectable::updateCandidateObj. Or for non-zyppers: The solver computed 'libvlc5;2.1.5-114.3;x86_64;VideoLAN' is converted into the 'best' libvlc5 available (highest version but same arch and vendor as the installed one). Is there a way to tell, whether the packageIDs passed to backend_update_packages_thread were (correctly) determined by a previous call to backend_get_updates_thread or whether it's the 'only allow to update candidates (fdo#61231)' case? -- You are receiving this mail because: You are on the CC list for the bug.
