recently I upgraded my Ubuntu to 21.04 using dev channel: sudo do-release-upgrade -d  (it was because I was curious of 21.04 and couldn't use -c flag because of ) where: -d, --devel-release               If using the latest supported release, upgrade to the development release  Now I wonder, am I using dev version of Ubuntu from now on? I would like to eventually use stable version of 21.04. How do I do that?

Update  appear to have been updated recently (as of writing this the last update appears to have taken place on 3rd of June) to include the following statement:  The -d switch is necessary to upgrade from Ubuntu 18.04 LTS as upgrades have not yet been enabled and will only be enabled after the first point release of 20.04 LTS.  Also note that .  TLDR (as of 15 Aug 2020):   is the canonical tracking document for the first Focal Fossa point-release (20.04.1). It’s a live document. The Ubuntu release team will be updating it as we work on releasing 20.04.1. […] Upgrades from 18.04 to 20.04.1 are still disabled as we are working through a few upgrade blockers   Edit The answers (so far) do not answer the question. The question is pretty simple. Ubuntu.com points to a &quot;FinalRelease&quot;, which turns out to be a &quot;Development Release&quot;, see evidence below. I'm not asking how and when to upgrade. I'm pointing out what seems to me to be an apparent inconcistency (in semantics, linguistics, logic) in the way Ubuntu names or labels its releases. From an answer to the question I'd except someone to pick up and acknowledge this inconsistency. An answer could start with a &quot;Yes, ...&quot; or a &quot;No, ...&quot;, for starters. (Moreover, a good answer could distinguish between the release being in dev stage and/or the upgrade process (e.g. from LTS to LTS) being in dev stage, if appropriate.) This question, as I see it, is not a duplicate. Futher, I think it is a question which deserves a non-patronizing answer. Thanks.   indicates that today (23rd April 2020) the new Ubuntu 20.04 LTS is to be released.  See &quot;condensed screenshot&quot; here:  Indeed, it seems that that's what happened, see  and :  However, when following the instructions to upgrade (from 18.04 LTS to 20.04 LTS) found  and elsewhere (edit: actually , too!), even prior to the July point release, I'm a bit confused to see that the instruction is to use update-manager -d which also points to the &quot;Development Release&quot; (see screenshot below) rather than the &quot;FinalRelease&quot; (see screenshot and link above). Is the &quot;Final Release&quot; (which I'm after) the/a &quot;Development Release&quot;? Why isn't it called something like &quot;Production Release&quot; or &quot;Final Release&quot;? When will it no longer be referred to as &quot;Development Release&quot;? In July? I'm confused :(

I just installed Ubuntu 12.10 (amd64), and want to install a recent version of MySQL 5.6.  If possible, I would like to install (not upgrade) it the "Debian Way' (i.e., using apt-get or dpkg).

What is the proper way to upgrade Ubuntu chroot environment to a newer Ubuntu release? The chroot environment has been originally set up using debootstrap.  The proper way to upgrade a Ubuntu server is to use do-release-upgrade command.  Ubuntu is based on Debian. Debian can be upgraded by replacing the release name in /etc/apt/sources.list with the new release name and running apt-get update, apt-get upgrade and apt-get dist-upgrade.  Which one is the proper way to upgrade a Ubuntu chroot environment? What does do-release-upgrade do differently from the Debian way?

From the usability point of view, I do not understand why on each release upgrade you have to manually patch all the URLs of apt in order to make them point to the newer distribution.  Why is not possible for apt to auto-detect the current and use it, so when you upgrade there is no need to upgrade the urls anymore?

I'm using Ubuntu 16.04.3 LTS, on a 64-bit system.   There are two available updates in "Updates" section of the Ubuntu Software, named OS Updates and Software respectively:      I usually update through Software Updater utility, (and occasionally used sudo apt update and sudo apt upgrade as recommended by some software installation tutorials)- anything that I think is required. So why is Ubuntu Software showing these updates? Should I install them?  As far as I know, these types of updates, if you look at the list, aren't ever available in the Software Updater.

I'm trying to install Ubuntu on my Nexus 7 (2012) Tablet, however, it appears that this tablet is no longer included in the official dev releases. I'm about half way through following the Porting to a New Device Guide and I'm just starting to realize how in-depth this project is about to become, so I was wondering if there was a way to find and install the last devel release for grouper.  This is the result that I got while following the install guide for Ubuntu Touch:  $ ubuntu-device-flash touch --channel=stable --device grouper --bootstrap  2015/06/08 12:48:59 Device is |grouper| Device grouper not found on server https://system-image.ubuntu.com channel stable   I also tried this with devel as well. It makes sense that a uTouch build for Grouper is not in either of these channels, as it is no longer officially supported.  As I'm not against taking the time to learn how to do this properly, if there is not a way to access a build for grouper, does anyone have some good articles to read or advice from their attempts at doing these sorts of things? This will be my first major foray into development or trying something like this.

I have an alpha version of Ubuntu.  When the stable version is released do I have to upgrade or is it already stable from the installed updates?

I have been trying to upgrade to Ubuntu 18.04 but when I try   do-release-upgrade -c   I get this output  Checking for a new Ubuntu release No new release found.   I have checked the release date to be 26th April but still, I didn't get any update...   I am a little new to Linux, so pardon me if I am mistaken on any point.

In the  of Ubuntu, I see that both the 14.04.1 and the 14.04 versions are offered for download. Do I need them both? That is, is 14.04 a prerequisite for installing 14.04.1? Or can I just download the last version ubuntu-14.04.1-desktop-amd64.iso?

I'm using Ubuntu 16.04 LTS on an Asus K53E laptop with 8 GB RAM. I check for updates to the software daily. If there are no updates, it asks me if I want to upgrade? What does upgrade exactly mean? Will my personal files still be there? Will it wipe EVERYTHING and give me a completely new installation of Ubuntu? Or will it allow me to keep my files and applications, and merely upgrade the OS?  When I upgrade my Mac or Windows machines, my personal files remain available after the upgrade. Does Ubuntu do the same, or are there completely different "rules"?

How to disallow Ubuntu to upgrade from like 11.10 to 12.04?  I know that its your wish if you want to upgrade, but I don't want the message in update manager that says a new release is available to get displayed.  All help will be appreciated

When I ssh into my  box, I get this message:  Welcome to Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-32-generic x86_64)   * Documentation:  https://help.ubuntu.com/  New release '12.10' available. Run 'do-release-upgrade' to upgrade to it.  Last login: &lt;redacted&gt; $   But I don't intend to upgrade to 12.10, because Mythbuntu recommends using LTS releases only.  How do I suppress the "New release '12.10' available" message?  I don't want to be notified until the next LTS release is available.  I've already gone to Update Manager > Settings > Updates and selected "Notify me of a new Ubuntu version: For long-term support versions", but that didn't get rid of this message.

I installed an Ubuntu alpha or beta and have been keeping it up to date.   So, Should I presume that my system has automatically updated to the next alpha or beta, and will be running the official release when it's finished?

I can't find any documentation on upgrading 16.04 to 16.04.1.  I'm assuming having all the package updates does it, but Details is still reporting 16.04 and there is still a 'developer options' tab in Software &amp; Updates, implying I'm still in some experimental release.
