All my disk space space has been taken up (400gb). Ubuntu Software Center will not allow me to remove anything.

Any ideas?

I suggest logging in as root and using a shell command line to see what is taking up the space and who owns it. As root, you should be able to delete unwanted files. If that fails, boot from CD/DVD and do the same thing.

rob@rob-GN561AA-ABA-a6230n:~$ gksudo nautilus

Error copying '/home/rob/.Xauthority' to '/tmp/libgksu-6lFZ7p': No space left on devicerob@rob-GN561AA-ABA-a6230n:~$

Where you've typed "gksudo", type this instead:

ls -ls | less

and page up and down what you see. Find a file you can easily recreate (maybe by downloading it again) that's over 10MB, and (change the filename from fred to what you've found)

rm fred

That'll free up enough space to get you into Nautilus with root permission.

If you need to first change to, eg, your Download directory to do the ls command there,

cd Download

For the future you might try installing a couple of useful command line utilities, mc and ncdu.

It looks like Dropbox, which I installed for my new Samsung Galaxy S3, was the problem. I uninstalled it, restarted and everything seems okay now.

It was weird because the Software Center wouldn't let me uninstall anything until I restarted.

I got into Nautilus as root but still can't get to the trash folder.

Once a system runs out of disk space, anything that was running at the time can crash and be left in a half-corrupted state. Sometimes reinstalling, or reconfiguring package will sync everything back up. This should force a package to reconfigure itself, like a fresh install:

dpkg-reconfigure packagename


I think trash can manually be deleted at /home/username/.local/share/Trash/files/ , but I haven't tested
