Is there any way to upgrade my distro from 14.04 to the development version of 16.04.
Using
update-manager -d
tells me about 14.10, which is weird since this version is not suppported anymore.
You have to use do-release-upgrade -d
(the -d flag to upgrade to a development version)
more info at Ubuntu Documentation
/etc/update-manager/release-upgrades
and make sure that the release upgrader is set to LTS using Prompt=lts
do-release-upgrade
. I upgraded this way with no problems.
