Proxmox Backup Server
Overview of install/config
This guy's YouTube tutorial was very helpful!
Changing the PBS admin password from CLI
Thank goodness I was able to change PBS user password from CLI because it's not as straightforward as one might expect.
TLDR: the actual correct syntax is:
proxmox-backup-debug api set /access/password --userid root@pam --password "Password"
The terminal will return null
but the password is changed (annoying).
warning
If you just do proxmox-backup-manager user update root@pam --password "MyPass"
the terminal will return a blank line. It will look like the password changed, but it hasn't. If you RTFM a little bit you'll learn that "This parameter is ignored." Whatever dude. That's annoying.
