I have a question which derived from a comment I got to another question. I know that LTS Ubuntu versions have support for 5 years so that means that Ubuntu 16.04 is supported up to 04/20.  If I replace the GUI of Ubuntu with another not supported version like mate (which I have done) without formatting is this considered an action that breaks the system and, thus, it is now considered Ubuntu mate instead of Ubuntu or not?

What happens if there is a security problem in a package in the universe repository four years after the 12.04 LTS release; will the package be updated from upstream, patched, or left alone?  It's my understanding that the "5 years of support &amp; security updates" applies only to the core of Ubuntu -- anything in Main repository.  Not for things in the Universe repository.    For a more specific example -- if I install Ruby now, and want to use it for the next several years on 12.04 and it has a security vulnerability; while this might be patched in the upstream (so I could always download the latest from their website and compile it myself or use a PPA), will this upstream fix be migrated into the precise package repositories? What about backports?

If there is a new release/major update of a program (e.g. Rhythmbox 2.97, Skype 4.0 or Gimp 2.8), is there an easy way to tell whether and when they will make it to the current official Ubuntu release repositories (especially to the LTS release, e.g. Ubuntu 12.04)? Or whether it will never be added to the official repositories, so I don't need to wait and just install it through an added PPA/repository?    I would like to use the program updates, but preferably when they are well tested and adjusted to the Ubuntu release I use (easily updated by the update manager). But some programs seem to never be added/updated and as I want to stick to the LTS release, I would need to add another repository. I know that there are restrictions to what will be updated (, ). But for example Firefox and Thunderbird are now regularly updated and Gimp 2.8 might be available in the backports. There is list of , but I don't find Firefox, Thunderbird (or Gimp) on it, although they are updated.  I just want to know how to find out whether there is an easy way to know (e.g. one webpage) which programs will be added/updated in the official Ubuntu repositories. Or do we have to ask a question on Askubuntu for every single program?

I havent used my Ubuntu for quite a long time.  Today, when I booted Ubuntu (14.04 LTS), the software updater and Software &amp; Updates (from Settings) are not working.  The software updater's window will show up for around 1 sec, but it will close automatically. Software &amp; Updates is never shown, no matter how many times I click the icon. Note that neither of them show any error message.  Those 2 features were working perfectly the last time I used Ubuntu. I want to do some system upgrade and update.  For now, I use sudo apt-get update &amp;&amp; sudo apt-get upgrade. This command runs very fast, meaning (I think) my Ubuntu is not updated properly. The update from software updater always has a big size hence the download should be slower.  What should I do?   Can I just uninstall and reinstall both of them? If I can, how to do it?  Just to clarify, I don't want to upgrade my Ubuntu version (I want the LTS one), I just want to upgrade the software/packages I used.  Thanks for your time.

that it will drop Unity 7 from Ubuntu 18.04 onwards, reverting back to the Gnome desktop environment. I know all the larger desktop environments quite well, Gnome, KDE and Xfce; however, Unity is the one I am more comfortable with and on which I I feel more productive.   I would therefore like to know if there any desktop environments forked from Unity 7 that could be installed on Ubuntu. I understand we are still one year away from the shift, but it is never too early to test the alternatives and eventually choose a project to contribute to.

I've understood that when I run the Software Updater GUI program, or when I execute do-release-upgrade on the command line, it should offer to upgrade to the latest LTS release if (1) I've got the release update behaviour set to lts, and (2) if the first point release of a newer LTS release is available. I have a couple of machines running the Xubuntu LTS release 18.04. The contents of file etc/update-manager/release-upgrades on all these machines is [DEFAULT] Prompt=lts  That satisfies condition (1). Also, it seems that Xubuntu 20.04.1 is already released, satisfying condition (2). However, neither do-release-upgrade nor the Software Updater offers to upgrade to that release. Why? Edited to add: It seems this question is a duplicate of .

There are so called "point releases" for LTS versions of Ubuntu. 10.04.3 for instance.  What are those "point releases" releases?

If you look at this  you'll see UNet is deprecated and will be removed in the future.  I'm developing a mobile multiplayer game, i've red official advise about it but they say "You can publish it with 2018.4 (LTS)" and I can't use 2018.4 version because in my project i use LWRP which is not in the 2018.X versions.  I've found the alpha version of the new system right    My questions are:  1- Should i use the alpha version of the new system? And can i publish my game with it?  2- Should i wait for the new system came out? (I can't wait for months)  3- Should i try to use other third party systems like Photon?  Or is there any way to publish my game with nice multiplayer system?  Note: I can't pay for multiplayer matchmaking system. Because of that i want to make Hosting multiplayer game.

I am running Ubuntu 14.04 LTS. Today when I logged into my computer I got an update alert saying that I could upgrade to Ubuntu 16.04 LTS. The other options were not now or do not upgrade. If I chose to upgrade will it delete my /home directories and the installed software under /opt and /usr/local ?

I am a bit confused about the release schedule of Ubuntu. AFAIK, it releases a new version every 6 months right? How about the LTS version?

If I install Ubuntu 18.10 (non LTS) now, then follow all the releases until next year where we will get the next LTS, will I (next year) be able to install the new LTS from my non LTS? I am not talking about downgrading, but upgrading to the next LTS from a non LTS system.

I recently upgraded to Ubuntu 16.04. Unfortunately I need to work MySQL 5.5 or 5.6. I tried many solutions to have MySQL 5.5 or 5.6 run on Ubuntu 16.04 like this  . But none of them is working. Ubuntu detect the unmet dependencies but says "but it is not going to be installed" for 5.5 or says Package 'mysql-server-5.6' has no installation candidate...  Is it not possible to force an earlier version of MySQL on Ubuntu? Why is that?

^^^^ Will Ubuntu GNOME upgrade to Ubuntu 18.04, or will support discontinue when 18.04 is released?? Just want to know what's better to run right now so I can upgrade and not have to reinstall later(I intend to see this transition through)-- GNOME installed correctly on vanilla Ubuntu, or Ubuntu GNOME?

Hai all I just want to know is there any Difference Between  and . I love to use Ubuntu... But I hate the Unity desktop... So want an Ubuntu system with GNOME 3. So if I install Ubuntu GNOME is that same as that of a usual Ubuntu with the GNOME desktop installed?  I just want to know, does this mean if I install Ubuntu GNOME 14.04.2 then everything other than the desktop is same as in Ubuntu 14.04.2?

I am after some advice with respect to the QGIS LTR schedule. Our IT managers have recently intervened in our use of QGIS (a State Government Authority) and are wanting to put in place a policy to only install and use the LTR release version, stating that the other releases are effectively 'Beta' versions. Their view is from a stability and security standpoint, not from training and process mapping (as that has nothing to do with them). I have seen and read this article -  Obviously the LTR has a slightly longer testing window so is less likely to have any major issues, but is their view that the other releases are 'Beta' version accurate or misled?
