Nautilus Fails to Start

view full story

http://askubuntu.com – I just upgraded my Unity to 5.0 , but it wasn't very stable, so I downgraded it using purge. But after recovering, I found that nautilus doesn't work. I tried to open it on terminal and got this: nautilus: error while loading shared libraries: libnautilus-extension.so.1: cannot open shared object file: No such file or directory I reinstalled it, but it didn't seem to work. I'd like to fix it and stick to it, if it's possible. What should I do? BTW, I'm using Ubuntu 11.10 64-bit. (HowTos)
