Dom0 failing to install packages

the sys-firewall can clearly find and cache the packages but when it gets back to the dom0 terminal everything that sysfire wall cancels out. This started happening recently.

Sudo qubes-dom0-update @kde-desktop-qubes

Module or Group 'kde-desktop-qube' is not available.
Error: Nothing to do

How do I fix this?

$ sudo qubes-dom0-update kde-settings-qubes

see I tried that and it didnt work but now all the sudden it does because I left my pc off through the day? I dont what it was but keep saying last checked meta data -1 day I tried when I woke up this morning and all the sudden it works? not sure what happened

would you also happen to know how I can make the font size work? for KDE? it seems everything became bigger when I installed Nvidia drivers. In the system settings I try to change the fonts and nothing at all happens.

I don’t use KDE so I don’t know.
Search the forum, maybe this question was already asked and you’ll find the solution.
