Hi @Reyfone!
Happy to see you testing ARM based builds.
Our ARM support currently is powered by ARM+LXD - so your single build job actually is running within LXD container. This means accessing certain system folders or features, that can give access to the whole LXD host, are blocked by apparmor due to security reasons. See one of the topics where it’s been explained already and our updated Multi CPU Architecture documentation
Please re-post a query for huge pages support within LXD as a separate topic in ARM CPU Architecture category so we could track it and handle the answer. We’re gathering feedback on various use-cases, including also the ones where LXD itself is not sufficient due to security constraints.
Hope it helps
