Backup Manager xmlSchemaParse() failed

[Szabolcs Hegyi]

Hello!

Since 12.5.30 update i have set up some incremental backups for some domains.
My "Backup Manager" and "Migration and Transfer Manager" now fail to open. ("xmlSchemaParse() failed" shows)
I can't see these packages in "updates and upgrades" menu, so i can't reinstall them.
I run Debian 7.9. Can u help me?

My pcmmcli.log shows:

Nobody? Its quite big problem for me since i have no backups now.
I've found 2 old threads in the forum about this problem, but they haven't answered.

Try to reinstall libxml2 and libxml2-python system packages at least.
