Setting up git user for ssh access

Install/Maintain/Configure
5
  1. my error message was “This account is currently not available.”
  2. I create user with this options:
adduser --system --group --disabled-password --home /etc/gitea gitea

without any shell.
The right way is:

adduser --system --shell /bin/bash --group --disabled-password --home /etc/gitea gitea

Thats why i can’t get via ssh.
