I recently found out that reboot works just as well as sudo reboot, from what I can tell. However, in a lot of instances, I see people saying to sudo reboot. Why is this? Are they the same, and just personal preference? Or are they different? Does sudo reboot do more than reboot?
Very confused on this one. Been looking around and all the answers I have found have been insufficient. Whenever I launch Nautilus, I get the error:
nautilus: symbol lookup error: nautilus: undefined symbol: gtk_flow_box_get_child_at_pos
The same thing appears when I try and use sudo nautilus or nautilus -q, or even sudo nautilus -q. I have tried enabling icons in Gnome tweaks, updating Ubuntu, updating GTK, reinstalling nautilus, and am out of ideas.
