Hi,

during upgrade to 42.2 I found a small dependency problem which is not resolved correctly with zypper (in my opinion) but probably I missed something. (Someone else just reported the same symptom in bugzilla but closed it again because he fixed it manually.)

Hygiea:~ # rpm -q --recommends MozillaFirefox | grep avcodec libavcodec-full >= 0.10.16

Hygiea:~ # zypper search -s --provides libavcodec-full

It returns nothing here with pristine Leap repositories.

i | libavcodec57 | Paket | 3.2-6.2 | x86_64 | Packman repository (Factory)

I think here is the problem. This output suggests that both variants for those package (openSUSE and packman) provide that. But this is not the case as can be seen here:

Hygiea:~ # rpm -q --whatprovides libavcodec-full libavcodec57-3.2-6.2.x86_64

Therefore this is a typical upgrade problem when the upgrade is performed via dup and non-official repos turned off which I would consider best practice but even if the packman repo is enabled again the recommended package is not automatically being pulled.

Is this a dependency resolving bug in libzypp or did I miss something?

Most likely libavcodec-full is provided by both versions of *Packman* package, later zypper displays all packages with the same name due to _"-s" flag.

Kind of what I expected

My guess also is that zypper reflects the result of the search to all packages with the same name

Without -s it just says: S | Name | Zusammenfassung | Typ --+--------------+----------------------+------ i | libavcodec56 | FFmpeg codec library | Paket

Hmm ... if this comes from standard repo, this looks indeed like a bug in zypper or some underlying library. I suppose nobody expected same package (name) from different repositories to have different set of provides.

i | libavcodec57 | FFmpeg codec library | Paket

What purpose serves this anyway, and does it actually work in practice? -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-packaging+owner@opensuse.org

If anyone knows a better or working solution to achieve the above, please let me know.

The well known 'zypper dup' will install the packman/videolan variants of ffmpeg, even without such extra Recommends. Olaf
