I have a problem with the tree snap, but when I emailed the current listed maintainer, I got a bounce email reporting that the email address does not exist. Is there someone I can contact about what appears to be a bug?
For context, the bug I’m having is with permissions. The snap is set to strict confinement with no interface for system-files. This appears to make it impossible to use tree on /var, /etc, /usr, and a few more directories, even as root. I’m updating university lab instructions to Ubuntu Server 18.04 LTS, where
tree is no longer in the default apt repositories, which means either instructing the students install their first Snap in dev mode or add the universe apt repository.
