Install SLES update on OpenSUSE

When I install a server I’m not to happy about doing upgrades…I don’t need new features and the risk of something not working after update is to high.
And OpenSUSE only provide updates for 6 (or is it 9) month.

But I wonder if it would be possible to subscribe to a SLES repositories and gets updates there from, as they provide update for many years?
E.g. using this URL:
http://download.opensuse.org/update/leap/15.6/sle/x86_64/
But I’m not sure If I can subscribe zypper to use this URL, secondly I don’t know if it will be updated when OpenSUSE 15.6 is EOL?

And then there is a question about versions.
If this should work I guess I should pick a version which SLES update for a long time, i.e. LTS release. On this page it seems the newest LTS release is SLE15 SP5.
But on Wikipedia is says 15 SP7 is supported to 31. july 2034! version|690x65
Now I’m a confused?

There seems to be much confusion on your side. This is already a standard repo which is used by Leap.

Where do you have this false information from?
Have a read:
https://en.opensuse.org/Lifetime
https://en.opensuse.org/Portal:Leap

Yes, of course I’m confused, that’s why I asking. If I was not confuse I would not do a post.

“Users are expected to upgrade to the latest minor release within 6 months”
I hope it is obvious we’re talking Leap

Are you saying the standard OpenSUSE repo, e.g. http://download.opensuse.org/distribution/leap/15.6/repo/oss/, will continue to be updated after 2025-12-31, it is my understanding it will not.

Of course I can upgrade to 16.00, but as I said, that’s not something you would like to do on a critical server (that’s why RHEL and SLES keep updates for 8-15 years, so you don’t have to)

(and by updates I mean security and bug fixes, that’s often all you need on a up-and-running production server)

The sentence continious after the comma:

leading to a maintenance life cycle of 18 months for each minor release.

Then you need to choose enterprise server solutions like SLES.

@MrBW the release cycle for SLES is the same for openSUSE, 18 months before a service pack release. Yes there is LTSS support for SLES, but I suspect many just go through the SP release and then can run LTSS. Note for SLES there is 15 SP7, no Leap 15.7.

Likewise moving to Leap has some additional hardware requirements, so if old equipment moving to leap 16.0 may not be an option, then you would need to look at Tumbleweed or Slowroll…

by the way, what is this repo?
https://download.opensuse.org/repositories/filesystems/15.7/
I assume the openSUSE maintainers made 15.7 packages…are these from SLES?

@MrBW likely for SLES Maintenance. Many leaf packages will over time be pushed to SLES.

off-topic, please delete, it bloat the thread (I specific asked about the opposite)
