[SOLVED]Thunar fails to launch

Just did full updates and thunar fails to launch after that with following error when run in terminal

thunar
thunar: error while loading shared libraries: libxfce4ui-2.so.0: cannot open shared object file: No such file or directory

how to fix this?

Try reinstalling libxfce4ui. It might just help:
sudo pacman -Syu libxfce4ui

Sounds to me like a partial upgrade. If you really did a upgrade maybe it was a mirror error. I'd suggest to refresh the mirrorlist and run an upgrade:

sudo pacman-mirrors -f 5
sudo pacman -Syyu

this did not help , now I am getting a bit different error output

thunar
thunar: error while loading shared libraries: libxfce4util.so.7: cannot open shared object file: No such file or directory

This did not help either

from this thread

Following command helped to fix the issue

Install both xfoncf and libxfce4util back :

sudo pacman -S xfconf libxfce4util
