Start by running this to get it all up to date for the current installed version
sudo apt update && sudo apt full-upgrade
If there are any errors shown then post it here.
Otherwise to upgrade to 19.04 use
sudo apt do-release-upgrade
but don't do that until the first command completes without error.
If that says no new releases found then open the GUI command Software
And Updates and in the  Updates tab check that Notify is set to 'For
any new version'.
