The Lenovo laptop has 23.10 fully updated till right now. I tried to do
sudo do-release-upgrade -d or with the --devel-release
and nothing happened, it only outputs
Checking for a new Ubuntu release
Upgrades to the development release are only
available from the latest supported release.
I also checked the /etc/update-manager/release-upgrades file and it is in normal mode set.
What could be causing this laptop to not be able to update to the development version for testing?
