I run my ubuntu 16.04 for my plex media server host. Yesterday I've done a plex update as I've allways done. Today I wanted to install the todays update and suddenly I get welcomed by "is not in the sudoers file" https://snag.gy/URMnj8.jpg
This VM has never seen anything else than plex and netdata. I've done a VM restart to no better result.
Any idea how I can get it back?
Thanks
