Yeah this is almost always the case, sometimes you have to wait until what you use supports the system underneath it. Way too many times I see people upgrading only then to find their application or whatever stopped working. There were differences between PHP 5.6 and 7.0 as well as 7.3, the same when going to PHP 8.0 or 8.1 the application that uses PHP also needs to be coded to work with the new version of PHP, for example.
It’s always best to check and verify that everything is going to work before doing such things on a production system especially.
Thanks very much chemal, this works a treat, fixes all the broken bits and Plasma starts in 2 seconds instead of 25…
Also good to use the Lock Screen again…
So with Rocky 8.6 kernel version 4.18.0-372.26.1 I tried several things and I was still having this issue. I check the journalctl and my issue was a file. The file /etc/authselect/system-auth only had read permissions. I changed it to 755 and the unlock function worked. I realize this isn’t a full fix for the bug but it turned out to be a good workaround for my situation.
