Issue Backup Manager (and migrator) not working after failed inplace upgrade

[BobClaas]

Im currently migrating from centos 7 to 8. Inplace upgrade failed and now the server has several problems.
since we werent able to fix them, we decided to migrate to a new server.

The migration tool failes on creating a backup file:

Failed to create the remote configuration dump on the target server. Not all settings may be migrated.
Error message: Command execution failed on the local server with non-zero exit code.
command: rsync -l --chmod=Fug=rw,Dug=rwx,o= --timeout=30 -e 'ssh -i /usr/local/psa/var/modules/panel-migrator/sessions/20240729010624/ssh-keys/id_rsa.XXX.XXX.XXX.XXX -p 22 -o PasswordAuthentication=no -o StrictHostKeyChecking=no -o GSSAPIAuthentication=no' [email protected]:/root/plesk_migrator/plesk_migrator-cre8nlip7dklvyeawiwoeon09zfkasb8/backup.tar /usr/local/psa/var/modules/panel-migrator/sessions/20240729010624/plesk.backup.source.downloaded.dump.tar
exit code: 23
stdout:
stderr: rsync: link_stat "/root/plesk_migrator/plesk_migrator-cre8nlip7dklvyeawiwoeon09zfkasb8/backup.tar" failed: No such file or directory (2)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1670) [Receiver=3.1.3]
rsync: [Receiver] write error: Broken pipe (32)

The file does not exist.
Going on the older server to the backup section, i get the following screen

500 PleskPMMResponseException​

Failed to parse response. Reason: Failed to read data from stream Process output:

Type	PleskPMMResponseException
Message	Failed to parse response. Reason: Failed to read data from stream Process output:

i tried repair tools. Uninstall en reinstall components like one drive backup.
I'm lost atm

ModuleNotFoundError: No module named 'lxml'

Try installing the missing lxml python module with pip3 install lxml

However there might also be an issue with the python version on your server. If installing the lxml python module does not solve the issue I would recommend opening a support ticket with out support team for an investigation of the issue. To sign-in to support and open a ticket go to https://support.plesk.com.

If you got your license from a reseller, your reseller should provide support for you. If the reseller does not provide support, here is an alternative to get support directly from Plesk: https://support.plesk.com/hc/en-us/articles/12388090147095-How-to-get-support-directly-from-Plesk

lxml is allready installed.
Requirement already satisfied: lxml in /usr/local/lib64/python3.6/site-packages

Will there be support when i buy it, cause i'm trying to migrate from CentOS 7?

How do you mean exactly?

 

[BobClaas]

How do you mean exactly?

Cause CentOS 7 is EOL.

 

[Kaspar@Plesk]

Yes, with CentOS 7 your are still eligible for support because we have Extended Lifecycle (ELS) Support for CentOS 7. Which can be purchased separately if you bought you Plesk license directly from our Plesk store. If you got your Plesk license via a reseller (for example your hosting provider) then ELS is automatically provided to you by your license reseller.

Does that answer your questions?
