First you want to ssh onto the server. There is a wiki directory there This wiki dir is the wiki repo, you can find it here https://bitbucket.org/errigal/wiki/
The wiki is run on a docker container managed by docker compose. There is a cronjob on this server that will back up all of the wiki contents to the repo.
You need to account for the plugins too.
So from the wiki.err (you are here now), sign in. Then Click Admin and figure out where the plugins are. Update all of them if you can. Then ssh onto the server, passwords in pwsafe.
Then cd wiki Then crontab -e Comment out the backup process
Then run docker-compose down && docker-compose up -d
Assuming the image maintainer has the newest image up, this will automatically update the process.
Use cat docker-compose.yml to double check
If all is well then crontab -e again and continue with the git backups.
