Hi - I am new to Arduino.
I have Linux Mint 19.3 MATE - and downloaded the IDE using snap.
From snap list…
arduino-mhall119 1.8.5 5 stable mhall119
The UNO seems to power up OK - and seems to have been allocated to /dev/ttyUSB0 ok.
The next step would be to Tools/ Get board Info - but “Native Serial Port, can’t obtain info” (ref attachment)
Dmesg has …
audit: type=1400 audit(1577806316.613:19607): apparmor=“DENIED” operation=“open” profile=“snap.arduino-mhall119.arduino” name="/sys/devices/pci0000:00/0000:00:14.0/usb1/busnum" pid=24356 comm=“java” requested_mask=“r” denied_mask=“r” fsuid=1000 ouid=0
I suspect Apparmor is causing the problem. I tried to stopping the Apparmor service but no change.
Any suggestions welcome.
