Trying to do a release upgrade on Ubuntu 14.04 with:

do-release-upgrade

I get the following error:

It was not possible to authenticate some packages. This may be a transient 
network problem. You may want to try again later. See below for a list of 
unauthenticated packages.

libxkbcommon-x11-0

What is this about? I did 

sudo apt-get update && sudo apt-get dist-upgrade

before and deactivated all ppas. What else could I do?

run this command 

sudo sh -c 'printf "[Distro]\nAllowUnauthenticated=yes" > /etc/update-manager/release-upgrades.d/unauth.cfg'

this will fix your issue

and after the upgrade run sudo rm /etc/update-manager/release-upgrades.d/unauth.cfg

  • Actually, you need `sudo sh -c 'printf "[Distro]\nAllowUnauthenticated=yes" > /etc/update-manager/release-upgrades.d/unauth.cfg'` because otherwise the redirection via `>` is not in the scope of `sudo`. – tillmo Dec 25 '16 at 16:40
  • Yeah. That's correct. I didn't execute the command. So I realized it after you pointed out the correction. I have updated my answer. Up-vote my answer if possible as it will help users when they have to refer this answer. – Tejus Prasad Dec 29 '16 at 02:05
