I have been working on this computer all day. The hlast thing I did was to add myself to the group dialout. I logged out and came back in. I tested that I had access to the serial port and went to install an app and I got this message " is not in the sudoers file. This incident will be reported." I have no access to anything root related

  • "I have no access to anything root related" - if this is true then you will not be able to run any commands as root/sudo. You need to be logged into a root account or an account in sudoers to add your user to sudoers. – Nmath Jun 30 '21 at 19:02

    You probably inadvertently removed your user from other supplemental groups (using usermod -G in place of usermod -aG for example). See How do I add myself back as a sudo user? – steeldriver Jun 30 '21 at 19:15
  • That is it, I did a "groups" and only see the dialout and my usergroup. everything else is gone. – ml41782 Jun 30 '21 at 20:12

    Be careful with edits to sudoers file, as any error is treated as if it's a EOF (end-of-file marker), ie. if you accidentally introduce an error in the file, all subsequent lines will never be used; which is why the visudo command exists (it checks for errors before you exit). If you don't have another account with sudo rights (or don't have root logins enabled), you can use a live media to correct the issue (it's what I'd use on this box, or as my system is dual boot I could correct from the other OS). – guiverc Jul 01 '21 at 00:07
