update from 14.04 LTS to 16.04 LTS using sudo do-release-upgrade -d

[Anthony]

I am currently using 14.04 LTS and I'm trying to upgrade to 16.04 LTS Alpha. Commands used: sudo apt-get update; sudo apt-get dist-upgrade; sudo apt-get upgrade; sudo update-grub; sudo do-release-upgrade -d. Starts to upgrade and says Aborted install and restores state back to 14.04 LTS. I am using a Toshiba Satellite C655D-S5518 w/ 4GB RAM(upgraded) and a 500GB SATA HDD(upgraded). Everything is functional for upgrades up to 15.10, but not to 16.04 Alpha. Used terminal to attempt upgrade and fail everytime. Also tried in shell mode without GUI, but still failed to upgrade to 16.04. Using Ubuntu 14.04.3 LTS that is up to date as of 10 minutes ago.

The option -D will put your machine into the development-release 16.04.

Just look at the last few lines of your attached log-file:

sudo do-release-upgrade and do-release-upgrade -d are similar, however, the
-d is for the latest dev version. April is right around the corner for the
"official" release of 16.04 LTS. Stick to what you are using and you may
find flaws that will take away from the Ubuntu experience. Stick with a
supported releases as to not to wind up with a broken HDD. Experiment on a
virtual HDD, like VMware and VirtualBox so as to not possibly break your
system.
