System Monitor does not launch
As suggested from comments:
snap remove gnome-system-monitor
sudo apt install gnome-system-monitor
worked for me.
I had the same issue. The gnome-system-monitor
is now available as a snap and it appears an update either broke something or didn't change everything properly (I don't really know why it stopped working).
A solution is to reinstall the snap (using snap
, not apt
) with:
snap remove gnome-system-monitor
snap install gnome-system-monitor
Doing this will install/connect the System Monitor properly and it will work once again from both icon and terminal.
