      I was installing docker-compose on my Cloudron installation and managed to break everything. Thinking that uninstalling docker-compose would fix it, I gave it a reboot and now I have multiple services failing to start.

      I cannot start unbound.

      MySQL and Nginx are running, and the files in /home/yellowtent/appsdata are intact

      Any help would be appreciated.

        @zezaung Looks like maybe uninstalling compose also nuked docker from what I can tell. The logs say docker.service: Failed at step EXEC spawning /usr/bin/dockerd . I guess that means the docker binary disappeared. Can you check if /var/lib/docker is still there? If that too is gone, we have to re-create all the containers (I can explain how to do this later).

        We install docker from the upstream repos directory, so download the 3 debs below and install them using apt install -y . docker_version below is 20.10.3 and ubuntu_codename is the output of lsb_release -cs

        https://download.docker.com/linux/ubuntu/dists/${ubuntu_codename}/pool/stable/amd64/containerd.io_1.4.3-1_amd64.deb
https://download.docker.com/linux/ubuntu/dists/${ubuntu_codename}/pool/stable/amd64/docker-ce-cli_${docker_version}~3-0~ubuntu-${ubuntu_codename}_amd64.deb

          If it helps, the relevant code we use is here - https://git.cloudron.io/cloudron/box/-/blob/master/scripts/installer.sh#L77 (but you cannot run the installer script directly since it's meant to be called from a new box update).

            @girish I can't thank you enough. Had some difficulties with the -o /tmp/filename.deb (it wasn't saving the file) so I downloaded and renamed the .deb onto my computer, filezilla'd to my home directory, then used mv filename.deb /tmp

            I restarted unbound and everything started running perfectly

            Here is the result:
            The lib files seemed untouched

            I hope this worked the way it should:

              Today I also managed to completely destroy Cloudron by installing Docker-Compose (apt install docker-compose) today. I think you should prevent exactly that during the installation.

                @johannesjom generally it is not supported to install other things via apt manually. There are some warnings about this when you SSH into your server, but we can't quite prevent users who have root access to their own server to install things or also change essential config files. So not sure what we can do here besides warning the user.
