Hey, please file a bug as explained on the ask ubuntu forum. I’m mostly interested in the following:
After installing the snap and attempting to run in it on the target system:
dmesg | grep DENIED
After logging in as intended user on the target system.
cat /proc/self/mountinfo
At any time on the target system.
snap version
Here target system is the system that will run the snap application.
