Solved Update CentOS to Alma on OVH dedicated

[websterPL]

So I have another server with DA and CentOS 8.4. After trying to update to Alma (https://github.com/AlmaLinux/almalinux-deploy) I see error code below:

Install almalinux-logos packages                                      ERROR
    OVH RTM repo                                    579  B/s | 193  B     00:00
    Errors during downloading metadata for repository 'OVH-rtm':
    - Status code: 500 for https://last-public-ovh-rtm.snap.mirrors.ovh.net/centos/8/x86_64/Packages/repodata/repomd.xml (IP: 213.32.5.7)
    Error: Failed to download metadata for repo 'OVH-rtm': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

Is there some solution for that problem with repo ?

If a remote URL gives HTTP/500 error, you can not fix it on your own. Just skip the mirror or disable the repository.

So I can just omit this and execute update to Alma ?

 

[zEitEr]

You might try it on your own risk. I can not say for sure the upgrade will go smoothly. If the upgrade script can not use another mirror, then the process will fail.

You might try clearing cache:

dnf clean all
dnf makecache
dnf check-update

and see whether it helps or not.

 

[websterPL]

Nope, always the same error "Errors during downloading metadata for repository 'OVH-rtm'". Thats mean that I will stay with CentOS 8 forever ?

 

[zEitEr]

Did you add the OVH RTM repo on your server for any reason? You might try and either disable or uninstall it.

 

[websterPL]

Hmm, after disable repo, the error is still showing but I see that Alma is already installed Should I reboot system now ?

[root@s1 ~]# yum repolist
repo id repo name
OVH-metrics OVH Metrics repo
OVH-rtm OVH RTM repo
appstream AlmaLinux 8 - AppStream
baseos AlmaLinux 8 - BaseOS
extras AlmaLinux 8 - Extras

[root@s1 ~]# yum update --disablerepo=OVH-rtm

Everything you do is at your own risk and responsibility. I can guarantee only work that I do my own hands.

If you are sure no critical error occurred during the migration, then you might try and reboot the server.

 

[websterPL]

So after reboot server is working on AlmaLinux release 8.8 (Sapphire Caracal), thx for help! But after "sudo dnf update -y" the 500 at OVH-rtm error still exist :/

 

[websterPL]

According to this article I removed OVH repo https://help.ovhcloud.com/csm/pl-de...?id=kb_article_view&sysparm_article=KB0058529

# yum remove ovh-rtm-binaries
# yum remove ovh-rtm-metrics-toolkit
# yum remove noderig
# yum remove beamium

Even after that OVH-repo is still showing and get 500 after sudo dnf update -y

 

[zEitEr]

I do know nothing about the repository OVH-rtm. I would rather remove it, if it does not work.

Even after that OVH-repo is still showing and get 500 after sudo dnf update -y

you might update cache then

 

[websterPL]

Ok its working now! Shouild read article to the end, THX
