Errors of creating a postgresql super user (with virtualbox)

[azaazafighting]

Does anyone know how to solve the problem when running install_all.sh:
OS: Ubuntu 18
Version: Postgresql 10 (cannot get resources for 9.1 as suggested)
Issue:
An error occurs when running the command
sudo pg_ctlcluster 10 label material start
Here is the error message:
Config owner (xxxx:1000) and data owner (postgres:126) do not match, and config owner is not root.

The installation stops when running the following command
sudo -u postgres psql -p 5433
Here is the error message:

psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s/PGSQL.5433"?

I'm not certain, but I believe I had a similar issue 2+ years ago.

Running that command as root/sudo didn't work for me. Instead if I changed user, i.e. sudo -u postgress pg_ctlcluster etc it worked. Possibly this helps.

Second, and this is probably useless information but: For me the cluster is called label_material. You can check /etc/postgresql/10 to see if clusters name really is without the underscore.
