Bug Description

Package opens, and lets me select packages to install, but when "Apply changes" button is clicked, an error dialog springs saying:
"This operation cannot continue since proper authorization was not provided".

This is a fresh installation of Lubuntu 20.04 and Muon did allow for installation of some packages like Musescore, VirtualBox, Calibre, ClamTk, Gimp and Rstudio. It suddenly ceased to work.

Also added these lines at the end of /usr/share/sddm/scripts/Xsetup

# Aqui trato de que ajuste mis monitores
xrandr --output DVI-I-1 --primary --mode 1680x1050 --pos 1024x0 --rotate normal --output DVI-I-2 --mode 1280x1024 --pos 0x0 --rotate left

so my left monitor starts rotated

Undoing this has not had any effect

googled a bit and found that Bug #1828663 pointed to an authorization problem arising from more than one user in sudo group. Removed all users but mine via CLI and it works again.

Seem to be a Qt authorization problem related to sudo group.
