Have you considered the cheaper LFCS (Linux Foundation Certified Sysadmin) instead? It might be easier for the company to "swallow" and it's more general Linux instead of mainly Red Hat based. I took it this year and it's pretty standard System Administrator stuff.

Was your phone also on your tailscale network while you tried to access it? If a device is on a tailscale network you need to be on the same tailscale network to be able to connect to it. Which likely means you need to add your phone to your tailscale network before the apps will access the server.

For me, KRunner has some quick actions for certain applications that I use a lot. Like a quick connect to a VPN service.

Maybe it puts KDE applications first?

Like the firewall thing, might be plasma firewall settings.

So... did you try installing those two?

If I'm not doing anything fancy and just use it for basic reverse proxy stuff for my docker containers, would I need to change stuff in the configs? Most of the stuff mentioned in the migration guide is about tls.caOptional stuff, which I don't believe I use.

https://tiddlywiki.com/ could also be an option. Although it's mostly for notes and such I think.

Does the same happen if the panel is at the bottom of the screen?

SOme OS's put it in the Grub/boot menu, but otherwise you can run it from a memtest live ISO like https://www.memtest.org/.

I don't know. If you feel like it's a bug, then open a bug report on bugs.kde.org.

It's not even an update, it's a rebuild to add a missing dependency.
