Trying the upgrade results in the following message:
"Could not download the release notes-Please check your internet connection"
My Internet is working fine. Having just downloaded various updates. Any suggestions how to fix this?
I had the same problem. If you open a terminal window (hold Ctrl+Alt+t) and type the following
do-release-upgrade
it will ask you for your password and it should automatically run the update
