I installed Natty and my perfectly functioning Ubuntu has stopped working - specifically, it has stopped reading disks. I think the problem has to do with Disk Utility not loading (though Ubuntu can see USB and DVD drives, but not mount them), so I tried it through command prompt and got this:
sudo palimpsest
libgdu:ERROR:gdu-pool.c:2369:device_recurse: assertion failed: (depth < 100)
lee@lee-desktop:~$
I'm not being lazy - I have now spent three days trying different things to fix it, Please Help!
