On your remote server, install the packages and create a git user:

$ sudo apt install git
$ sudo adduser git

optionally add your public key to access the repo for automatic SSH authentication:

git@server.com:~$ mkdir ~/.ssh && touch ~/.ssh/authorized_keys
user@local-workstation:~$ cat ~/.ssh/id_rsa.pub | \
    ssh git@server.com "cat >> ~/.ssh/authorized_keys"

Create a bare new local repo:

git@server.com:~$ mkdir my-repo
git@server.com:~$ cd my-repo
git@server.com:~$ git --bare init

The new repo is ready to be cloned:

user@local-workstation:~$ git clone git@git.myserver.com:my-repo.git
