- I created a Linux user called "admin" and put it into the "root" group".
- I created a user in the Proxmox UI called admin and put it into the "admins" group.
- I log with the admin account and the "Upgrade" button is grayed out.
- If I login as "root", the "Upgrade" button is not grayed out.
What permission am I missing for the Proxmox "admin" user?
