Tried to upgrade my computer from 13.04 to 13.10, but directly after pressing the upgrade, a couple files appear to download, and then the window disappears and nothing happens...
I tried it from the terminal window and this is the output (same result)
jessijo@halesite3:~$ update-manager
Checking for a new Ubuntu release
authenticate 'saucy.tar.gz' against 'saucy.tar.gz.gpg'
extracting 'saucy.tar.gz'
Real-time signal 0
Any ideas?
