Hi, Yt tells me I have to install the gtk+ interface, not originially on my os installation before it can install. To do this I have to load a bunch of things not native on my os, which is Ubuntu (linux). Soon as I have the gtk+ installed then I get a quirky error booting up: There was an error loading the theme Human. Couldn't recognize the image file format for file '/usr/share/gdm/themes/Human/bottom_bar.svg' on a login screen that is not the original Ubuntu login screen. I can login okay and everything runs as normal, also Yt, so far (just command line). Is there any way the origin of this quirk can effect Yt? I'm searching forums for my and tracing the problem on my system but just wondering if anyone more familiar with the Yt interface might know off-hand. Below are the extra loadings for Yt involving gtk+.
