I don't know how, but I was upgrading from ubuntu 11.10 using:
sudo do-release-upgrade -d
Then after the upgrade and a reboot, I did:
sudo lsb_release -a
and got:
No LSB modules are available.
Distributor ID:
Ubuntu Description:Ubuntu Trusty Tahr (development branch)
Release: 14.04
Codename: trusty
How was this possible? Is it possible to downgrade without a rebuild? I guess I'm an alpha tester for 14.04 now?
-d, --devel-release
Check if upgrading to the latest devel release is possible
so it exactly that and upgraded to the latest development release.--devel-release
in documentation, not the cryptic abbreviations like-d
. I did the same thing. :(
