Configuration instructions for gitea install from snap store are required.
sudo snap install gitea really doesn’t seem adequate - given my experience with the result.
ubuntu@gitea:~$ sudo snap install gitea
[restart]
ubuntu@gitea:~$ sudo systemctl status gitea
Unit gitea.service could not be found.
ubuntu@gitea:~$ sudo systemctl daemon-reload
ubuntu@gitea:~$ sudo systemctl enable --now gitea
Failed to enable unit: Unit file gitea.service does not exist.
You can use Gitea with SQLite by default with the snap without installing other packages. Any other databases you will have to install and configure additional packages. If this is going to be large installation or performance is wanted, it is better to use alternate database like PostgreSQL or MariaDB.
