As usual, no problems with any of the updates for any of the computers, but a funny thing happened when I updated my Xfce laptop. I'll explain ...
When I upgrade my laptops, I restart the usual applications in their workspaces, and when I'm done with the Xfce laptop, I hibernate it and put it away for now. (Still using the Plasma laptop for a daily driver.) This time, all of the applications started without an issue except Thunar. I couldn't launch it from the dock or from the menu. Since this has never happpened before, and I'm not currently depending on that computer, I'm happy to see how things go after the next update.
Strangely, though, I wanted to see if the Xfce VM (which I'l previously upgraded and then shut down) would share the problem if I tried to start it, and the answer was no. On the VM, Thunar launched immediately. To be honest, those Thunar installations are not exactly the same.
As I'm preparing the Xfce laptop to be a duplicate of my Plasma laptop, it also mounts my 12 NAS shares, and it replaces the usual folders in my /home folder with NAS shares that are named the same, e.g., Documents, Downloads, Pictures, etc. Symbolic links provide those folders from the relevant shares in /mnt. And this scheme has never failed me before.
The VM, on the other hand, is meant to be used in helping new users, possibly providing screenshots to illulstrate how to do things. It's very much an out-of-the-box installation - in other words, no NAS, no shares replacing /home folders, or any other such modifications.
So, no problem with any of the updates, but I've still got some debugging to do, when I have time.
