Catfish file search - updating data base asking for authentication as superuser

[Moltke]

I've been doing it selectively for years with stable programs like thunar and gedit, without issue, foresee none

Those days are coming to an end, and there are several important reasons why, and it is not good advice to encourage new users toward a praxis that involves purposely deprecated software like gksu. It's about like recommending Windows XP over Windows 10. The often referenced mission statement for Linux Lite is to create a Linux software environment that new users coming from Windows can easily transition to. It's certainly counter intuitive here to encourage the inexperienced Linux user to use bad or deprecated tools. Go argue about it on the Deb channels: http://forums.debian.net/viewtopic.php?f=20&t=144101 but please not here, where the new inexperienced user is the most important.

I wasn't aware gksu is now deprecated. A web search showed some results and we're suppose to use pkexec or something like gedit admin:///etc/default/apport according to this article https://itsfoss.com/gksu-replacement-ubuntu/ I tried the latter and I got a blank file. I did via the app finder/launcher tool with alt+f2, same result via terminal. The pkexec approach didn't work either with the app finder/launcher tool, when tried in the terminal got this error

Code:

polkit-agent-helper-1: pam_authenticate failed: Authentication failure
==== AUTHENTICATION FAILED ===
Error executing command as another user: Not authorized

And yes, I'm 100% sure I typed in the right password. So I guess will continue to use gksu or sudo, I do have the option in the right-click menu to open thunar as root as well as the terminal though. Why do they change the questions when we already know the answers?  8)
