i’m trying to build a Ubunt Bionic based image for a Edge board but my host is Ubuntu Focal. I thought that the Fenix Docker would allow this, but it does not. I’m now trying to build a Docker image based on ubuntu:bionic to run fenix in a Bionic container. First part of the build goes well but the build stops at
Failure trying to run: mount -t proc proc /proc
any idea on how to get this to work ?
