The issue here is that the release was built in Alpine and is being deployed to Ubuntu, and includes ERTS - that won’t work. You need to either not include ERTS, or build in an Ubuntu container/VM/etc. I would recommend the latter, since if you have NIFs, they may also be sensitive to the difference. Hopefully in the future we’ll have a way to build “linux generic” releases, but that is not the case today.
