OS version: Ubuntu 20.04 x86_64

Distro: Ubuntu 20.04.6 LTS

Things that I have tried:
Rebooting server
Plesk repair fs -system (which is where we had some errors) but it failed to repair see below for command results
Plesk login command but I get the following message on the web: The file /opt/psa/admin/htdocs/application.php is part of Plesk distribution. It cannot be run outside of Plesk environment.
Submitting a ticket to Plesk support, but the license was detected has coming from another seller (in this case it's hetzner).
Tried contacting hetzner but they wouldn't help us, they said to contact Plesk.......
Tried paying for the Plesk support, which supposedly gives us support independently of where the license was bought, but for this specific license it didn't work.
Plesk installer update
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
mod-security-v3 : Depends: libyajl2 (>= 2.0.4) but it is not going to be installed
plesk-backup-utilities : Depends: python2 but it is not going to be installed
plesk-core-utilities : Depends: python2 but it is not going to be installed
plesk-php73-snmp : Depends: libsnmp35 (>= 5.8+dfsg) but it is not going to be installed
plesk-php73-tidy : Depends: libtidy5deb1 (>= 1:5.2.0) but it is not going to be installed
plesk-php74-dev : Depends: plesk-php74 (= 7.4.33-ubuntu.18.04.221109.1443) but 7.4.33-ubuntu.20.04.240507.1400 is to be installed
plesk-php74-snmp : Depends: libsnmp35 (>= 5.8+dfsg) but it is not going to be installed
plesk-php74-tidy : Depends: libtidy5deb1 (>= 1:5.2.0) but it is not going to be installed
plesk-php82-snmp : Depends: libsnmp35 (>= 5.8+dfsg) but it is not going to be installed
plesk-php82-tidy : Depends: libtidy5deb1 (>= 1:5.2.0) but it is not going to be installed
psa : Depends: python2 but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).






Installation will not continue


ERROR: The 'apt' utility failed to install the required packages.
Not all packages were installed.

exit status 1

apt --fix-broken install

I didn't proceed with it cause it wanted to remove a bunch of Plesk packages that I thought could be important

The following packages will be REMOVED:
  plesk-config-troubleshooter plesk-core plesk-l10n plesk-roundcube plesk-web-hosting plesk-web-socket psa-horde psa-imp psa-ingo psa-kronolith psa-mnemo psa-passwd psa-turba psa-updates psa-vhost

Tried a few more things that I can't remember right now, but I will update as I remember it.

I get an Apollo error code 400 as I try to login to Plesk on the web.
