Endeavour OS - Cassini - Plasma

I created this VM this afternoon, because I wanted to see whether an updated version of it might allow me to access my remote NFS shares. The first time I evaluated this distro, I was unable to, no matter what I tried. Sadly, that problem persists, and for what it's worth, this problem is unusual among the distros I've explored recently. In Endeavour, I actually set the ownership of the /mnt folder and its contents to jerry:jerry, which should give me full access, but I can't enter a single share.
Aside from that, I encountered no problems installing this, updating it, and configuring it. I installed Thunderbird and Vivaldi, of course, and the three games I enjoy. Because I intend to keep this VM around for a while, and experiment with it, I installed the Plasma DE (sorry, Brent). That's just one of seven choices that the Calamares installer offers for an online installation.
If anyone would like to explore a DE you're not currently using, here are the choices that the installer offers for an online (Internet) installation. From the download page:
The offline option installs a fully themed Xfce and the online option provides you with the choice of seven Desktop Environments Xfce, Mate, LXQt, LXDE, Cinnamon, Plasma, Gnome, Budgie, window manager Openbox and tiling window managers i3-WM, BSPWM, Sway, Qtile and Worm.
The online option apparently does an update as it installs, because when I tried to do that in the terminal with PacMan, I was told there was nothing to upgrade.
Because I've reviewed this distro already, I'm not going to spend a lot of time on it again. but if anyone has a specific question about Endeavour OS, let me know, and I'll do my best to get you an answer. Finally, here's the obligatory system info from neofech:
