Fedora 38 Upgrade From Fedora 36

[David Dembrow]

Is it safe to upgrade to fedora 38 from fedora 36?  Or in other words 
can a release cycle get skipped?

It is not recommended. Safest to go via 37.

That is not correct.  See the link that Jeffrey posted.

"System upgrade is only officially supported and tested over 2 releases 
at most (e.g. from 36 to 38)."

I have upgraded 2 releases at a time many times with no issues.

I have got away with it too.  Went two at
a time from 33 to 37 last year at
a customer site.

Actually, I went F34 -> F38 last night, without any issue. Just added a --nogpgcheck.

So, I have this circa 2009 Dell Precision T7710 and the HDD died. I put in an old SSD and brought it back. However, for some reason, it does not boot off of a live CD that is newer. I had one F34 lying around, and got it booted off that. Then I  did

sudo dnf update --releasever 38

and it went through the download and then failed at the key check. So, I tried by removing the check and it went through.

sudo dnf update --releasever 38 --nogpgcheck

After installation, it asked to verify the key for F38, and that was permitted, and it appears to be like another machine that has been able to follow a more disciplined regimen. I tried this on a whim some time ago with another old machine (F34 -> F37 in that case), and it worked then too. I guess this is not recommended, but it worked for me.

Thanks,
Ranjan

The Fedora signing keys are located at  /etc/pki/rpm-gpg. I wonder if
you could have copied the missing keys manually, or if the signing
algorithm was the problem.

Thanks, that is a good point. I could have done that, I guess, but it would have been more work. So, I gave the nogpgcheck to update, and then verified once the update to the higher release version happened.

I can see why this would not be recommended. I think that my case was safer because I used the F34 to install and then immediately moved to upgrade to F38. No non-Fedora repos were added before the upgrade.

Many thanks and best wishes,
Ranjan

See https://docs.fedoraproject.org/en-US/quick-docs/dnf-system-upgrade/
. The topic is discussed.
