As you’re all aware, and per https://www.centos.org/centos-linux-eol/ , CentOS Linux 8 is going EOL end of this month, and content will just remain available on mirror network until January 31st.
After that date, CentOS Linux 8 repositories will be removed from mirror network, and mirrorlist will start answering “invalid release”, so no way to easily install any rpm component.
But what about SIGs content that was built for/against CentOS Linux 8 ? (basically other repositories that you can see under http://mirror.centos.org/centos/8/ but that aren’t coming from centos linux 8 distro itself ?
As soon as CentOS Stream 8 was announced, we offered the possibility to all SIGs to opt-in and build for/against Stream 8, and so have their repositories automatically pushed to http://mirror.centos.org/centos/8-stream , as it was for /8/ .
Most of the SIGs opted at that time to build in parallel for 8 and 8-stream, while some decided to just start building against/for 8-stream directly (and of course content built on 8-stream *should* just work fine, and reverse is also true)
But some months ago, community members asked (https://pagure.io/centos-infra/issue/400) if that was possible to continue building against/for el8, but so switching buildroot from centos 8 to RHEL 8, which was worked on and is now available.
What does that mean for you, SIGs ?
If you want (opt-in and so optional) continue to build for el8, just create a ticket on https://pagure.io/centos-infra/issues to ask your tags to build against RHEL 8 instead of CentOS Linux 8. You can do that whenever you want but before (for obvious reasons) end of January 2022
What if you don’t opt-in ? You SIG content will removed from mirror network, at the same time as CentOS Linux 8 content.
So to recap :
* End of january, *all* repositories listed under http://mirror.centos.org/centos/8/ will be removed (except for SIGs that opted-in for the ‘switch to RHEL 8 buildroot’ plan) * mirrorlist.centos.org will also start answering ‘invalid repo’ for SIG content, as it will be for CentOS Linux 8 itself * All SIGs tags for 8 will be locked down (except for SIGs that opted-in for the ‘switch to RHEL 8 buildroot’ plan) so no way to just tag-build (and so push anything) out
