QuoteI've been doing it selectively for years with stable programs like thunar and gedit, without issue, foresee noneThose 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. TC

I checked those screenshots you shared and noticed that in one of them reads that the database ...
sudo chmod 666 /var/lib/nlocate/mlocate.db
sudo chmod 644 /var/lib/nlocate/mlocate.db
So what does this mean with respect to "IF" I do wish to update the catfish data base, what must I do/type?
gksu catfish
That'd be gksu working. Gksu is a graphical frontend for sudo that allows graphical command to be run without the need to run an X terminal emulator and using su directly. It's effectively just a GTK+ skin for the superuser commands. Try this so you see for yourself; press alt+f2 which will launch app finder tool, type sudo thunar and click on run, then type gksu thunar and click on run, what did happen in both cases?
Does Install Updates work when you enter your password?
Here's another thought: Let's use synaptic as an example. Most of us open synaptic from the menu, then get a popup asking for our root pw. If, instead, we used a terminal and called it with "sudo synaptic," other than not getting the popup asking for the root pw, would it operate any differently? I doubt it. I'm guessing the same would be true with catfish asking for the root pw.
Open Lite User Manager and see how many users are listed in the drop down box. Then see which ones have the sudo box ticked or unticked. Sent from my Mobile phone using Tapatalk
It's better to use gksu than sudo for GUIs apps
Running graphical programs using sudo in Ubuntu is basically fine – in many cases. However, in some freak cases it might cause problems! However, I have not encountered these myself yet.
