I am running Ubuntu 14.04 64bit on my Dell XPS 13 laptop, and up until now I was able to start nautilus via terminal or by using ALT+F2 and typing
gksu nautilus through Dash. Only now, supposedly after I upgraded the system via update manager where unity package got updated, I cannot do it anymore. When trying to launch it via ALT+F2 I can see a cogwheel moving instead of a cursor, and if I do it with terminal
gksu nautilus it shows me this
gksu nautilus ** (gksu:6420): CRITICAL **: fcntl error ** (gksu:6420): WARNING **: Lock taken by pid: -1. Exiting.
if I launch it with
sudo command, everything works as expected.
The question is, is it a bug (which means I will report it immediately), or is it a known issue and there is a workaround I can try already?
