[SOLVED] Critical error when trying to upgrade from Proxmox 7.4-17 to 8 (custom role will clash)

[Yakov]

Hey, I was following the guide to upgrade my Proxmox server from version 7 to 8, so I performed a dist-upgrade so I could check with the pve7to8 checklist script.

I ran pve7to8 -full, and it reported with this:

PASS: systemd unit 'pveproxy.service' is in state 'active' PASS: systemd unit 'pvedaemon.service' is in state 'active' PASS: systemd unit 'pvescheduler.service' is in state 'active' PASS: systemd unit 'pvestatd.service' is in state 'active' INFO: Checking for supported & active NTP service..

Try to solve the problems one at a time and then run this checklist tool again.

I've searched the forums and I couldn't really figure out what: FAIL: 1 custom role(s) will clash with 'PVE' namespace for built-in roles enforced in Proxmox VE 8 means.
As far as I know I have a pretty vanilla configuration so I am not really sure what could have caused this error, any help would be greatly appreciated.

Fixed it.
I may have created a role called PVENetwork ages ago and forgot to delete it, unsure why it caused problems but it's not needed anymore and deleting that role has cleared the problem.
