change /etc/upgrade-manager/release-upgrades Prompt=lts to Prompt=normal, it should help.

Hi there I've gone through the stages you've described here, but I keep getting an error message: ' Checking for a new Ubuntu release Get:1 Upgrade tool signature [198 B] Get:2 Upgrade tool [1,147 kB] Fetched 1,148 kB in 6s (77.0 kB/s) authenticate 'utopic.tar.gz' against 'utopic.tar.gz.gpg' gpg exited 2 Debug information: gpg: Signature made Tue 21 Oct 2014 14:09:03 BST using DSA key ID 437D05B5 gpg: Can't check signature: public key not found Authentication failed Authenticating the upgrade failed. There may be a problem with the network or with the server. I am using a pitifully slow public wifi in my local library - could that have something to do with it?

You have a typo in your how-to:

sudo do-release upgrade

Should be:

sudo do-release-upgrade
