I have a user in Debian 11 that I created through the GUI. However, when I attempt to add this user to a group, it says the user does not exist. I’ve successfully logged in to this user, so I’m unsure why it’s giving me this error.

In reply to dragonmouth.

Actually you can, but it is not recommended anyway…

try,

$ sudo usermod -o -u 0 username

and this user will have now the same id as the root user.

Yep, the issue could happen if you assign that id, try on a virtual machine, and everything should be fine…

Then the UID number assignment depends on the distro you are using. I use PCLinuxOS and the default starting UID number is 500. From my distro-hopping days, I remember that some distros allow the admin to set the lowest allowable UID and/or the highest allowable UID.

In reply to dragonmouth. @gragonmouth, As per security standard it advised to use above 1000 UID/GID. Moreover, 0-1000 reserved for System users by default in Systemd (RHEL 7, CentOS 7, Oracle Linux 7 etc. )Linux servers. Try to create a user and notice you will find UID/GID will be above >1000.
