I've checked this thread [solved] How to prevent password prompts? - #5 by Aravisian but obviously, the solution doesn't work anymore as stated there. There's a temp fix, but I would like to know how to fix it properly.
So I edited visudo to look like this:
# User privilege specification root ALL=(ALL:ALL) ALL # Members of the admin group may gain root privileges %admin ALL=(ALL) NOPASSWD: ALL # Allow members of group sudo to execute any command %sudo ALL=(ALL:ALL) ALL x ALL=(ALL) NOPASSWD: ALL # See sudoers(5) for more information on "#include" directives: #includedir /etc/sudoers.d
but Software app still shows password prompts once I want to install something. How to disable those, as it's a frustrating experience to type 20+ chars on every installation?
