How to Upgrade from 14.10 to 15.04 [closed]

1

Ubuntu 15.04 beta 1 has been released closely following the Ubuntu 15.04 release schedule. If you want to experience the new features being introduced in Ubuntu 15.04 beta, we’ll see how to upgrade to Ubuntu 15.04 beta from Ubuntu 14.10 in this post.

A word of caution, this is not a stable release. You’ll definitely face several issues and bugs. I would suggest you not to upgrade to Ubuntu 15.04 beta now and wait for the final release, if you are looking for a stable system. Because you can not downgrade back to Ubuntu 14.10, once you have upgraded to Ubuntu 15.04. You would need to reinstall Ubuntu 14.10 or 14.04. You have been warned ;)

Upgrade to Ubuntu 15.04 beta from Ubuntu 14.10

I have written this tutorial using Ubuntu 14.10 Unity. But the same procedure is also valid for other official Ubuntu flavors i.e. Xubuntu, Kubuntu, Lubuntu, Ubuntu Gnome, Ubuntu Mate etc. Just follow the steps below:

I'm looking for a way to upgrade 14.10 to 15.04 - from the internet only (i.e. without using external media).

I've already tried apt-get dist-upgrade

Ubuntu 15.04 is not available yet and will be available in April. If you really want to test it you can download the daily build iso from here although this is highly unstable now.

After the release you can upgrade from 14.10 to 15.04 by running the following command:

sudo do-release-upgrade

I would not recommend this but if you really want to upgrade to the latest development release:

sudo do-release-upgrade -d

EDIT :

As Ubuntu 15.04 (Vivid Vervet) has been released on 23rd April, 2015, you can upgrade from Ubuntu 14.10 to 15.04 easily...

Ubuntu 15.04 Vivid Vervet is the upcoming latest version of Ubuntu. The stable version of Ubuntu 15.04 has not been released yet. According to the Ubuntu 15.04 release calendar, it is supposed to be release in the month of April 2015. If you want to test this OS you can download and install beta 2 (unstable release) with the help of external media. Ubuntu 15.04 Beta 2 ISO file is available for download on the official site of Ubuntu.
If you have Ubuntu 14.10 installed, then you can upgrade it to Ubuntu 15.04 Vivid Vervet easily. Ubuntu 15.04 is still in beta phase so I would recommend you to wait a little and enjoy the full stable release. But if you still want to test the OS follow the steps below. The same procedure will work for the installation of final stable release.

Problem

I update my laptop from 14.10 to 15.04 a few days ago. And now it is boot with strange problems. It is terrible but after reboot I have password-free root access to my Ubuntu in terminal. For some reasons systemd failed to boot, and throw up shell with root prompt.

“Ask yourself: ‘Do I really need to upgrade right now?'”

So if you’re wondering how to upgrade Ubuntu 14.04 LTS to Ubuntu 16.04 LTS, read on; we’re here to walk you through the process step-by-step.

Is Performing an LTS-to-LTS Upgrade Recommended?

Like the version you are upgrading from, Ubuntu 16.04 is a Long Term Support release. It will receive critical bug fixes and security updates from Canonical for 5 years.

A device running Ubuntu 14.04 LTS will only tell you there is a new Ubuntu update after the first point release goes live. In Xenial’s case that’s July.

Today, July 23, was the last day when Canonical released security patches and software updates for its Ubuntu 14.10 (Utopic Unicorn) operating system, as the distribution reached end of life.

Dubbed Utopic Unicorn, the Ubuntu 14.10 operating system was announced by Canonical back on October 23, 2014 and was supported with software updates, bugfixes, and security patches for nine months. On July 23, 2015, the 9-month month support cycle officially ended and the software channels are now closed.

Additionally, Ubuntu 14.10 users are being informed by Canonical that new Ubuntu Security Notices will no longer include information about the Utopic Unicorn distribution. Users need to take all the measures required to prepare their system for a possible upgrade to the current stable version of Ubuntu Linux (see below for details).
