I know this question have been asked so many times before, but I think my case is a little bit different, my username is “vu”, I added myself to the dialout group by “sudo usermod -a -G dialout vu”, I also logged out and logged in, but it still didn’t change anything, the error still there.
Then I tried a few command to check if I already in the dialout group, “groups” with no username is supposed to be showing groups that the current user are in right?, but as you can see it only show I’m in the group “vu” and “wheel”, then when I do the “groups vu” it shows “vu wheel dialout”, could this be the problem?, I’m pretty new to linux so I really have no idea know what’s going on lol
