### Bug Description I have a snap for Core 22 that builds like a charm on x86. However, when I am trying to build on ARM, it fails. I believe it gets blocked at lxd stage. ### To Reproduce You can check out the code from here: git@github.com:skidoomanubuntu/oval-core-tools.git Then, just snapcraft on an ARM machine BTW, I tried a few variations. Going to multipass was not successful, neither was invoking sudo snapcraft. ### Environment I have an ARM server with 64 cores from ADLink, so I assume my system's scalability is not an issue. uname
