Hi, I run a small self-hosted forum on a 25GB cloud VM running Debian 13. I was attempting to update to 2026.6.0-latest using ./launcher rebuild app and the update cancelled because I didn’t have enough disk space. I followed the prompt to clean up Docker images, but that didn’t help. I have 3.9 GB …

It’s worth running a cleanup. Please post details of what happened. Here’s one I once did: root@ubuntu-2gb-nbg1-1:/var/discourse# df -h / Filesystem Size Used Avail Use% Mounted on /dev/sda1 19G 12G 6.5G 65% / root@ubuntu-2gb-nbg1-1:/var/discourse# ./launcher cleanup WARNING! Thi…

This will remove all images without at least one container associated to them. Are you sure you want to continue? [y/N] y Deleted Images:…

You’ve just cleaned up two bases images leaving the local built image.

Are the base images just remnants of the original installation process? Or do they get downloaded during a rebuild app as well?

Yes. The latest image is downloaded if missing and you will build your local image from there. I can’t think of a reason why you might want to keep more than one base image …

[imagen] long_season: 2.5G /var/log/journal Still a big saving possible here.

Sí. Si la imagen más reciente no está disponible, se descargará y a partir de ella construirás tu imagen local.

No se me ocurre ninguna razón por la que podrías querer mantener más de una imagen base…
