While trying to upgrade through the web interface the installation broke. On investigation the disk space is kind of low, which is surprising, since it is a really small forum with not much content on a 40 GB server.
I ran ./launcher rebuild app in the console, but this always fails because of not enough space.
How can I revive the forum? Even if I do the cleaning of docker images the next time I run it results in the same.
Did you answer yes to letting it get rid of the unused containers? There’s a reasonable chance that’ll restore a bunch of space.
You can do a ./launcher cleanup. You should first do a ./launcher start app and make a backup. That way, if things go south you can just spin up a new server and restore the backup. If your server has been around, it might be time for a new OS anyway.
