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.

 ![The image displays a terminal command line interface showing operating state updates and messages indicating insufficient disk space, along with a prompt to clean up Docker images and containers.

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.

I did answer yes, but it goes back to the same prompt.

Then you’ll need to free up space some other way.
