PVE 8 to 9 In-place Upgrade

Did you actually read and understand the part of the upgrade guide that leesteken not only linked to but even quoted?

Did you manually install and setup systemd-boot?
If no, you should follow the advice of the pve8to9 script and remove the systemd-boot meta-package.
Afterwards check the output of the pve8to9 script again; especially in regards of the systemd-boot-efi and systemd-boot-tools packages. (Afaik, they both should respectively have to be installed in your case...)
 
I have read the upgrade guide many times, I don't know if I manually installed systems-boot as it was so long ago, many years, and I may have had help from someone at the time. So If I remove systemd-boot and then run the script, will it then tell me before any reboot if I need to install system-boot-efi and systemd-boot-tools?
 
yes. you can tell if you manually installed it - if your ESP is managed by proxmox-boot-tool, you didn't. if it isn't, you did.

Most likely, you did not...

Exactly this is mentioned in the relevant part of the official upgrade guide.
Don't know which guide you have read, but it seems it is/was not the official one...:

Good luck...
 
OK So I removed systemd-boot last night, rant the script again before and after the updates and nothing else was reported or needed installing, rebooted, and the host came up fine, now on 9.2.21. Thank you all
