Resolved Can't restore backup in plesk 18.0.56 Element 'server: The attribute 'guid' is required but missing."

[marcin690]

I had to reisnatalise the system. The new plesk is installed in version 18.0.56, the copy is from version 18.0.55, I can not open it because of the error "backup_info_2310120013.xml:
Line 1535 error: element 'server': The attribute 'guid' is required but missing."

I also can't extract the archive to manually restore the pages because it is in the TZST extension.

What to do in such a situation? I couldn't find a command to install plesk version 18.0.55

Hi @marcin690, this is a brand new issue that was discovered on Friday. It's been filed with our highest priority as a hotfix under PPS-15083, PPPM-14162, PPP-62834, PPP-62848. The issue is that a a backup created on Plesk versions prior 18.0.56 cannot be restored to 18.0.56 or newer. The hotfix is already in the making, but I do not have an ETA yet. Unfortunately, there is no known workaround.

If you want to unpack a .tzst archive, please see this KB article that describes how you can do it on your system:

Can I install plesk version 18.0.55?

You cannot downgrade Plesk to a previous version. Currently, there is no known workaround for the issue.

As a German hoster "Strato" is facing a downtime of his VServers for more than 72 hours, I was setting up a new server and was facing the above mentioned issue.

My workaround now was to install plesk 18.0.54 (the version of my backup file) using this instruction:
How to install a legacy Plesk version - Support Cases from Plesk Knowledge Base

Now I am able to restore the server without the above mentioned issue. Hope this helps.

Same problem here, also same problem with Strato.

Unfortunately I wasn't able to install a lower version than .56 since it's the only one listed when following the instructions on the link you mentioned, @hilutions .
How did you achieve this?

I was using an entirely new server that I just rented. But just this morning I received the information that Strato solved the issue after 4 days of downtime.

Me too, but .56 was installed and no chance to go back.

Didn't get any info yet from them (on a non-self-hosted domain). My server rebootet, yes, but I still have the same mail issues - imap not working on the server. Still no mails from my own domains.
Tried a direct migration but it also failed. Maybe same issue due to version mismatch?

If plesk has been installed before, there is no way of going back. I was reinstalling the entire machine with a clean Ubuntu 22, then did all the updates and then started the plesk installation wich that all version - option.
