Hi all,

I am getting the below error when trying to run a rebuild to upgrade to most recent test-passed. This would include bumping the postgres version from 13 to 15.

```plaintext

fi

debconf: delaying package configuration, since apt-utils is not installed
cp: cannot stat '/etc/postgresql/13/main/*': No such file or directory

```

The script just becomes stuck at this copy command.

When I try to restart the forum, restart command completes successfully but the forum is showing “connection refused”.

How do I either rollback to use my backup in postgres 13 or move forward? Thanks
