      Hi,
      I'm forked Writefreely to add a CloudronManifest.json file and adjusted the Dockerfile to install it in my Cloudron instance. The Docker image builds successfully but when Cloudron tries to run it, I get the following error when it runs box:shell reload spawn: /usr/bin/sudo -S /home/yellowtent/box/src/scripts/restartservice.sh nginx:

      standard_init_linux.go:228: exec user process caused: exec format error
      

      I did a bit of search on the internet and it turns out the restartservice.sh might be missing the shebang and therefore the OS doesn't know how to execute the script. I replaced the Alpine image with Ubuntu's and the issue persists so I'm not quite sure what I can install/configure in the OS for that script to run successfully. Any ideas?

      Thanks in advance,
      Pedro

        @pepicrft I'm not sure this will make a difference but generally recommended to build the Dockerfile using the cloudron base image

        FROM cloudron/base:3.2.0@sha256:ba1d566164a67c266782545ea9809dc611c4152e27686fd14060332dd88263ea

        Could try that out

          @timconsidine thats what I tought too but the offical documentation not even mentions the Cloudron base image.

          Have you took a look at other packed go apps for Cloudron? Is the user you exec with correct (because just a /usr/bin/sudo -S feels wrong)?

            @pepicrft run.sh needs to be an executable i.e chmod +x in the repo.
