[Spacewalk-list] Spacewalk server keeps resyncing same packages from channel

[Wenkai Chen]

HI Michael,

Thanks so much for the insight. Should I configure separate channels for all different distributions (updates,OS,extras) or just updates and OS will do?



Regards,

Hello,

If you download the two packages
http://mirror.centos.org/centos/7/updates/x86_64/Packages/pki-base-10.5.9-6.el7.noarch.rpm
http://mirror.centos.org/centos/7/os/x86_64/Packages/pki-base-10.5.9-6.el7.noarch.rpm
you can see they have different size and buildtime.
414392  'Fri 02 Nov 2018 20:05:20 CET' os/pki-base-10.5.9-6.el7.noarch.rpm
414396  'Tue 29 Jan 2019 18:47:13 CET' updates/pki-base-10.5.9-6.el7.noarch.rpm
So what's actually happening there is: you sync pki-base from os, then overwrite it with version from updates; and then during the next sync you overwrite it with os version and once more with updates version, etc.

IMHO it's Centos bug - a package from os should never be (without version-release change) rebuilt into updates.

I'd recommend to create a separate child channel for updates and do not mix os and updates rpms into one channel.
