Using PolKit to rescue sudoers failure

[@Maniac_0470_]

With the rest of the community - I am so sorry for your loss - its been awesome seeing your videos keeping her front and center for so long. On a slightly lighter note - I REALLY liked this video - very quick and definitely any Linux administrator should know about - could literally save a system or business!

Thank you so much, just a week to go to mark her passing. Your comments will mean a lot to her family

the best solution I've seen, and I'm sorry to say that it happened to me and I had to ask backup to restore sudoers

Nice to know so thanks for showing me this, but surely you could just "su" to root using root's password? Or just login as root at the console.

[@theurbanpenguin]

Many cloud systems do not have a root password. So su and console are out. By default Ubuntu systems never have root password

[@sadasulna6056]

@@theurbanpenguin In which case you can just su to root without a password, surely?

[@theurbanpenguin]

@@sadasulna6056 by default in Ubuntu and many cloud images there is no root password. If you have access to the physical system you can reset a root password but this is not possible on cloud systems. Setting a root password is never desirable which is why Ubuntu does not and many cloud systems.

Cool! If I understand correctly, this is basically a replacement for sudo, right? I have tested it on my local system, and when I run the pkexec command, I get a pop-up window requesting my credentials, just like sudo would do, but with a gnome window instead. Cool! I also tried it on a remote system unsuccessfully. Running "pkexec visudo" as the user "akadmin" who is a member of the "wheel" group returns: $ pkexec visudo ==== AUTHENTICATING FOR org.freedesktop.policykit.exec ==== Authentication is needed to run `/usr/sbin/visudo' as the super user Authenticating as: Ak Admin (akadmin) Password: polkit-agent-helper-1: error response to PolicyKit daemon: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: No session for cookie I must have missed something... in any case, thank you for your videos!

you have to have two consoles.one to run the agent to monitor the terminal that you run commands from
