Issue re Authentication failure

Post by w19 » Tue Feb 12, 2019 4:24 am

I installed mint a few days ago. Today, I am able to login but my password is not recognized for any authentication request (e.g., when requesting to run Synaptic Package Manager). In the log, I receive the following two messages:

pam_unix(polkit-1:auth): authentication failure; logname= uid=1000 euid=0 tty= ruser=root rhost= user=root

w19: Error executing command as another user: Request dismissed [USER=root] [TTY=unknown] [CWD=/home/w19] [COMMAND=/usr/bin/env DISPLAY=:0 XAUTHORITY=/home/w19/.Xauthority timeshift-gtk]

Does anyone have any guidance? I'm new to linux and at a loss.

What's your output from the command

Code: Select all
