Updated to Lemmy Release 0.19.12

The instance has just been updated. There was a slight hickup with web-ui which has been fixed. :)

Alongside the update, I started with a lazy little Ansible playbook. Curious folks are welcome to have a look at the repo. Don't expect anything special, complete or tidy - right now its only purpose is updating the instance. However i think i will add some more config templates to it asap (like systemd, webserver). This instance does not run on Docker, therefor (and for other reasons) the official playbook does not apply. :)
