hello I'm a Linux noobster and I am tryig to learn how to use the "gedit" command for programming purposes, but I have this issue after I open a new document
rob@Satellite:~$ gedit program.c
(gedit:11872): Gtk-WARNING **: Theme parsing error: gtk-widgets.css:2:16: Theming engine 'adwaita' not found
(gedit:11872): Gtk-WARNING **: Theme parsing error: gtk-widgets.css:1443:2: Missing name of pseudo-class
I want to know, what does that means? and what am I doing wrong here?
thanks for everything
