I’m on Fedora Silverblue 42.20250828.0. I’m trying to add my user to a group, but the command doesn’t seem to be working…
me@fedora:~$ sudo usermod -aG dialout $USER
me@fedora:~$ su - $USER
Contraseña:
me@fedora:~$ id
uid=1000(me) gid=1000(me) grupos=1000(me),10(wheel) contexto=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
I even tried rebooting my laptop, but when I log back in and run id, I get the same output as above.
I’m trying to get access to this device on my laptop.
$ ls -alh /dev/ttyACM0
crw-rw----. 1 root dialout 166, 0 ago 28 14:22 /dev/ttyACM0
I got that command from here: Managing Users and Groups :: Fedora Docs
Here’s some more group info from my system. I see dialout listed.
