GUI won't let me open files as "Open as Administrator" if logged in as another

[member=6629]ralphy[/member]  Essentially gksudo is deprecated for security reasons on all gtk3+ apps in gnome so it is inconsistent across platforms based on Ubuntu 16.04 and up and/or Debian 9. The deployment of pkexec is incomplete in Ubuntu 16.04 and up as well, depending on the version, so that XFCE, Mate, Lubuntu, and others can still access gksudo for certain other apps. It is an Ubu thing. Similar issues with NM and WICD since Deb default went gnome, i/e gnome default compared to LXDE. Core issue is with the base GUI for apps.

I agree [member=5916]trinidad[/member]  , it hasn't been maintained since 08-09 and deprecated. In Ubuntu it is jus a symbolic link to gksu. pkexec is been in Ubuntu since precise. Just hadn't been widely adopted for the reasons you stated. pkexec is pretty much available across platforms today and even Ubuntu derivates have switched fully to pkexec. E.g.: Ubuntu-Budgie does not have gksu/do installed out of the box.
