Constant maintenance no.
Currently I have some issues with the Nvidia driver acting up. So I am getting good at purging it and reinstalling it. Maybe once a month.
Under Ubuntu desktop.
My server I have very little issues. For mye Proxmox environments I have a small issue after restart it doesn’t properly month a NFS share. If I don’t do mount -a.
My laptop I have a constant issue that hibernating don’t work with encryption out of the box. So I have to turn if off or connected it to power. I think there have been mad some progress but I haven’t reinstalled Ubuntu for 2 years.
