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.

  • It's unclear (at least to me) how you are launching nautilus when you get these errors. Are you attempting to launch a GUI application via the command line? – Elder Geek Feb 5 '18 at 19:07
  • @ElderGeek I am launching it by just putting nautilus into terminal, as launching the application via the Ubuntu desktop GUI, it loads for a second then crashes. (i figured it was running into an error, so i am launching it via console to see the error) – Zeke Egherman Feb 5 '18 at 19:13
  • @davidfoerster done. – Zeke Egherman Feb 6 '18 at 1:20
  • Digging a bit deeper, how about ldd $(which nautilus) | grep gtk, readlink -f /usr/lib/x86_64-linux-gnu/libgtk-3.so.0 and nm -D /usr/lib/x86_64-linux-gnu/libgtk-3.so.0 | grep flow_box_get_child – steeldriver Feb 6 '18 at 2:51

You have a second installation of libgtk3 in /usr/local/lib that is incompatible with Nautilus (and likely other GTK applications from the package repository). Please either remove that GTK installation altogether or remove /usr/local/lib from the default search path for shared libraries.

I recommend the former (deinstallation of the GTK library) as it appears you don't know how it got there which means it likely servers no (more) purpose:

  1. Go to the source code directory from which you originally built and installed the GTK library to /usr/local/lib. It should contain a file called Makefile or GNUmakefile.

  2. Invoke its uninstallation routine:

    sudo make uninstall
