This is restricted because it provides privileged access to configure serial port hardware. It’s better than nothing but it surely would be best to run it confined with allowed access to serial tty devices.Ĭan access serial ports.

Until the serial-port gadget/interface is improved to give access to all system serial devices you can get your snap working by simply installing it non-confined like so: $ snap install tio -classic Some interesting links that helped find the answer Note: info below are needed for old Arduino 1.6.10. You should now have access to your serial ports! Happy Hacking! Install the snap in classic mode to allow access to ports $ snap install arduino-mhall119 -classic See this answer for up to date info on how to get serial working with the arduino snap. The arduino-mhall119 snap is outdated and should not be used anymore. $ cat /snap/arduino-mhall119/current/meta/snap.yaml |grep -A 5 plug $ cat /snap/arduino-mhall119/current/meta/snap.yaml |grep -A 12 slots Information about YAML-manifest: $ ls -l /snap/arduino-mhall119/current/meta/snap.yaml $ snap connect arduino-mhall119:/dev/ttyUSB0Įrror: snap "arduino-mhall119" has no plug named "/dev/ttyUSB0"Įrror: cannot resolve connection, plug snap name is empty The following do not work too (because of syntax errors): $ sudo snap connect arduino-mhall119:arduinoĮrror: snap "arduino-mhall119" has no plug named "arduino" :x11 arduino-mhall119,organize-my-files,pulsemixer,vlcĬhanging permissions of serial port to 777 with sudo chmod 777 /dev/ttyUSB0 does not help. :unity7 arduino-mhall119,gedit,organize-my-files,vlc :network arduino-mhall119,gedit,organize-my-files,pulsemixer,vlc :home arduino-mhall119,gedit,organize-my-files,vlc

Update: connecting serial-port to the snap fails with the following message $ snap connect arduino-mhall119:serial-portĮrror: snap "core" has no "serial-port" interface slotsĬurrent interfaces are: $ snap interfaces | grep arduino So my question is: How to make Arduino (Snap) access serial port /dev/ttyUSB0 (or /dev/ttyACM0)? Note: we already have similar question here, but the solution was to use package from umake, not fix for the Snap. See for suggestions.**Īlso I have installed arduino 1.8.5 with umake - it can access serial port in usual way. I tried to upload the simpliest Blink sketch and get the following errors in the terminal: $ arduino-mhall119.arduinoĪvrdude: ser_open(): can't open device "/dev/ttyUSB0": Permission denied I connected my Arduino Nano to the laptop, it is detected on port /dev/ttyUSB0 ( ch341-uart). Username adm dialout cdrom sudo dip plugdev lpadmin sambashare I have added my user to dial-out group and rebooted: sudo usermod -a -G dialout $USER I installed Arduino IDE v1.8.5 as a snap with snap install arduino-mhall119
