Edit homeassistant container

Hi forum,
I modified the run.sh script on the hope to be able to achieve some special addon.
Unfortunately, I’m stumbling on a error so the HA doesn’t start at all.
I’m trying to get into the docker container to recover the backup, but if I use my Archlinux amd86_64 I can’t access, due by the different architecture.
Am I right, or it is possible?

I’m trying to access from my Tinkerboard, but I can’t share two network at the same time, because I’d like to access the container headlessly. If it won’t be possible, then I will plug the TB on the TVset :woozy_face:
