I have a debian box, and after some version update or so, root commands are not recognized while being in the desktop environment; for instance dhclient or reboot.

At first, I took it as an additional security measure. But using gparted via an direct system access without desktop (eg using a Ctrl-Alt-F1 login) does not make much sense.

 $ uname -a Linux terbium 4.19.0-17-amd64 #1 SMP Debian 4.19.194-3 (2021-07-18) x86_64 GNU/Linux $ cat /etc/debian_version 11.2 $ su Password: # root@hostname:/home/user# dhclient # example bash: dhclient: command not found

Is this documented behavior or just update error? or system error? Any idea where to start or how to solve this?

[edit: To make sure I explained right: some root commands work on desktop for instance apt, but others work only on the desktop-free shell, eg dhclient or reboot ; and gparted is in limbo ...]

  • Check your shells config and login files Commented Mar 2, 2022 at 14:16
  • If you do su -, you'll get root's environment -- the hyphen specifies a login shell. Commented Mar 2, 2022 at 15:45
  • @glennjackman thx ! I was just doing su ... So how come I do not have the same rights in this case? [edit] ok, it's documented in man su ... Commented Mar 3, 2022 at 9:06
