update from 5 to 7 problems

[zika]

Hello
I want to upgrade proxmox 5.1 to 7 versions.
I am editing the repositories, taking into account that debian stretch has been moved to the archive, it is updated to 5.4 correctly. I'm rebooting.

next, I run the script pve5to6 - everything is ok.
next, I change the repositories to a buster, make "apt update", "apt dist-upgrade" and see

The following packages have unmet dependencies:
 pve-cluster : Breaks: pve-ha-manager (<= 3.0-3) but 2.0-9 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

update it to version 3.0-3 (apt install pve-ha-manager=3.0-3) and see
