Comment # 8 on bug 1041443 from Jeroen Pluimers

Thanks all for the comments: I've learned a lot (:

To summarise:

- kernel-default 4.4.68-7.1 (old) was installed from @System
- kernel-default 4.11.1-1.1 (current) was installed from
openSUSE-Ports-Tumbleweed-repo-oss
- both are from a different vendor
- --no-allow-vendor-change dislikes the vendor difference and doesn't know what
to do with kernel-default 4.4.68-7.1, but in the message forgets to tell there
also is kernel-default 4.11.1-1.1 which is current
- without --no-allow-vendor-change there is no problem: it allows the vendor
difference


Aren't @System and openSUSE-Ports-Tumbleweed-repo-oss are effectively the same?
If so: shouldn't the solver treat them like that?



For my own reference so I can query this stuff myself in the future:
