Looks like you’re on Fedora Silverblue (or other Atomic version). This is happening because the system groups are in /usr/lib/group rather than /etc/group and this causes the issue you’re seeing here. You can work around it by getting into a root shell with something like
sudo -iand then getting the group added to /etc/group with
grep -E '^dialout' /usr/lib/group >> /etc/groupafter that, you’ll be able to add your user to the group with
usermod -aG dialout pipeRight on the money, that’s what I ended up doing. Thanks!
Is that considered a feature for some reason? That seems objectively terrible.
No, it’s a side effect of how everything’s handled by rpm-ostree currently, and it’s on the list of issues to be fixed.
Why can’t we keep system config things in /etc? It’s a method that works in unsurprising ways.
Is etc the mutable part? Would you have to do this again to add more users after a reboot?
/etc is writable, so no reboots are required. That said, /etc is treated in a special way and each deployment will have its own /etc, based on the previous one.
So if you make changes to /etc then revert to a previous deployment, your changes will be reverted as well. But if you make changes and upgrade (or do whatever to create a new deployment), your changes will bu preserved.
That’s really helpful to understand the caveats, thank you.
It’s like when I run into some issue with how I’ve set up my system in NixOS and have to explain to a non-Linux user that it isn’t Linux that’s the issue but how I’m using an especially weird Linux lol
If you want to add an existing user to an existing group, use:
usermod -a -G <group> <user>I like
gpasswd -a <user> <group>
I’ve had this one recently.
It gives you an error message, but creates the group anyway.
(some!) FOSS developers when you open an issue about it: works for me. Closed
(Disclaimer: I know not all foss devs are like this. Especially kde devs are awesome.)
Well, I didn’t report it (I’m not sure even how to categorize it), so I really don’t know how it would go.
TBH, I don’t even know what project hosts useradd. Never looked that up.
Even if “isn’t that bad” were true, it’s hardly a stunning endorsement. I wish Linux aimed higher than “not that bad”, but it always seems to hit “only some bits are broken”.
