Insufficient permissions, please make sure the device file is read- and writeable!

Hi. I’ve had my Atreus for a few weeks now but only just now plugged it in to start trying it out. I downloaded the Chrysalis AppImage but upon running it I get the error “Insufficient permissions, please make sure the device file is read- and writeable!”. I’ve already tried reloading my session and even completely restarting per Chrysalis Error After Upgrading to Ubuntu 20.04.1 LTS but no dice. What do I do? (Debian)

Hi rmlrml. I found help for the same problem here:

Yeah I linked to that post in my question, but upon re-reading I realized I skipped the part about adding myself to dialout. I’ll try it when I get home from work.
