I want to upgrade Ubuntu 14.04.3 LTS to Ubuntu 16.04 LTS.

First I run

sudo apt update
sudo apt dist-upgrade

Then I checked Ubuntu running version:

cat /etc/lsb-release

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty
DISTRIB_DESCRIPTION="Ubuntu 14.04.3 LTS"

and then I started Ubuntu 16.04 installation with

sudo do-release-upgrade -d

which threw the following error:

The required dependency 'apt (>= 1.0.1ubuntu2.13)' is not installed.

I know that first I need to upgrade Ubuntu 14.04.3 LTS to Ubuntu 14.04.4 LTS and then to Ubuntu 16.04 LTS. But unable to upgrade Ubuntu 14.04.3 LTS to Ubuntu 14.04.4 LTS. I would highly appreciate if someone help me in this regard. Thanks

I tried:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get -f install
sudo apt-get -y install apt
sudo do-release-upgrade

But still getting the same error. Any help will be highly appreciated. Thanks

  • Waow.I didn't know about this method.I thought the upgrade will only be done when the software updater states that a new version of ubuntu is ready.. – john400 Aug 20 '16 at 06:04

    Check [this question and it's solution](http://askubuntu.com/questions/777013/14-04-16-04-failed-apt-1-0-1ubuntu2-13-is-not-installed). It will be solved. Make sure you first upgraded to 14.04.4 using `sudo apt-get dist-upgrade`. Then do the `do-release-upgrade` – Anwar Aug 22 '16 at 14:31
