Open 'Software Updater' and upgrade online. On slow connection it would take some time. Have patience. It would be seamless. All your apps would remain as it is.

dist-upgrade is not a good choice for upgrading from 13.10 to 14.04.

try sudo do-release-upgrade for you upgrading, according to the official document here:

Wiki on Upgrading

I upgraded to 14.04 successfully yesterday in this way.

update

if the speed of update is slow, the mirror site of ubuntu update has not gotten the 14.04 pacakge. try to change a mirror site:

open preferences -- software and update, change a website near your country listed in 'download from'.

And I also searched the keywork 'could not calculate the upgrade', try these suggestions if you still field to upgrade ubuntu.

    Could not calculate the upgrade

    An unresolvable problem occurred while calculating the upgrade.

    This can be caused by:

    • Upgrading to a pre-release version of Ubuntu
    • Running the current pre-release version of Ubuntu Unofficial software packages not provided by Ubuntu
