Error when installing Gitlab


I have an Ubuntu Server with Plesk installed.

When I want to install Gitlab with the recommended “curl” line, I always get this error message:

Running handlers
There was an error running gitlab-ctl reconfigure:
    execute[/opt/gitlab/embedded/bin/initdb -D /var/opt/gitlab/postgresql/data -E UTF8] (postgresql::enable line 80) had an error: Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but received '1'
    ---- Begin output of /opt/gitlab/embedded/bin/initdb -D /var/opt/gitlab/postgresql/data -E UTF8 ----
    STDOUT: The files belonging to this database system will be owned by user "gitlab-psql".
    This user must also own the server process.
    STDERR: initdb: invalid locale settings; check LANG and LC_* environment variables
    ---- End output of /opt/gitlab/embedded/bin/initdb -D /var/opt/gitlab/postgresql/data -E UTF8 ----
    Ran /opt/gitlab/embedded/bin/initdb -D /var/opt/gitlab/postgresql/data -E UTF8 returned 1

Has anyone an idea to fix this?
