Oh, wait. I see this is a known issue.

How to add myself to the dialout group?

I need to add myself to the dialout group for the Arduino IDE flatpak to be able to upload code to my micro-controller which is connected via USB. $ ls -lah /dev/ttyACM0 crw-rw----. 1 root dialout 166, 0 Oct 25 12:34 ttyACM0 I have tried running this command as root: grep -E '^dialout:' /usr/lib/group >> /etc/group and then running this command. useradd -aG dialout $USER But, that last command does not add my user to the dialout group.
