I try this to upgrade but just get an error:

nick@netbook:~$ sudo update-manager

Checking for a new Ubuntu release

WARNING:root:file 'trusty.tar.gz.gpg' missing

nick@netbook:~$

The GUI just says:

Failed to fetch Fetching the upgrade failed. There may be a network problem.

There is not a network problem, all other network stuff works and this has been happening for weeks.

Any idea of what actions I should take to sort this?

Cheers
Nick

Check the following things:

Update your sources.list file. You can get a fresh copy from this website if you are in doubt.

If you are behind a proxy server, add -E with sudo to preserve the environment variables.

Now your commands will be

sudo -E apt-get update

sudo -E apt-get dist-upgrade
