Resolved Plesk Update issue after debian upgrade

[Deleted member 190513]

Hi,

I just upgraded from Debian 8 to 9 and now Plesk cannot update its componenets.

I've looked at this gudie which hints that my sources are wrong.
Unable to upgrade/install Plesk on Ubuntu/Debian: the following packages have unmet dependencies

I currently use these:

deb http://deb.debian.org/debian stretch main contrib non-free
deb http://security.debian.org/debian-security/ stretch/updates main contrib non-free
deb http://deb.debian.org/debian stretch-updates main contrib non-free

After I updated I could not run /opt/psa/bin/distupgrade.helper.deb7-deb8_post.x64.sh since the file wasn't there. Could that be the cause? If so - How do I fix that?

Please help

UPDATE:

Solved with these commands:
# plesk installer --select-release-current --reinstall-patch --upgrade-installed-components
# plesk repair installation
