How to fix broken sudo - sudo: parse error in /etc/sudoers near line X
pkexec vi /etc/sudoers/...
Running pkexec without a graphical agent fails even with falling back onto pkttyagent
running pkexec gives something like:
polkit-agent-helper-1: error response to PolicyKit daemon: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: No session for cookie
==== AUTHENTICATION FAILED ===
Error executing command as another user: Not authorized
Note that to make it work, run pkttyagent in a different terminal binding to
the PID of the first terminal that is running pkexec.
In the first terminal run the following command to get its PID.
In the second terminal run
pkttyagent --process PID_FROM_STEP_1
In the first terminal, do whatever you need to do with pkexec.
