I can't upgrade to Ubuntu 18.04 from 17.10
Solution 1
Upgrading from Ubuntu 16.04 LTS or 17.10
Upgrades from 17.10 will not be enabled until a few days after 18.04's release. Upgrades from 16.04 LTS will not be enabled until a few days after the 18.04.1 release expected in late July.There are no offline upgrade options for Ubuntu Desktop and Ubuntu Server.
That's the official announcement from Bionic Beaver release notes
Hope this helps.
Solution 2
I had the same problem. I am not an expert but after reading various posts I tried these commands and finally got my system to start the update:
xhost +
sudo xhost si:localuser:root
sudo update-manager -cd
This problem is related to Wayland. Maybe an expert can explain.
Hope this works for you...I know this can be frustrating :-)
