Good day,
following instructions I modified the .yaml file and left plugs: [serial-port].
When trying to run the application it crashed and the system logs i could see several apparmor DENIED logs. Reading through the forums I was able to clear some apparmor DENIED logs by adding desktop, desktop-legacy, network, network-control plugs etc, etc.
One issue I have is apparmor DENIED for ‘/run/systemd/resolve/resolv.conf’. A suggestion on How to modify name resolution parameters from a snap? is to add the plug for system-files and this requires to be manual reviews.
Can I get system-files permissions to pass automatically? @alexmurray
