I am unable to open any files/folders on my system. I was getting lots of errors while opening nautilus and I entered the following command based on this.
sudo killall nautilus && (nautilus &)
After this, I am unable to even right click on the desktop and not even select any files on the desktop. There are 2 or 3 similar questions on this site regarding this issue, but none of them have been answered.
What can I do?
EDIT: As asked in the comments, this is what I get when I run the 'nautilus' command:
(nautilus:2399): GLib-GIO-CRITICAL **: g_dbus_interface_skeleton_unexport: assertion 'interface_->priv->connections != NULL' failed
