I am using Ubuntu 10.04 LTS. I want to upgrade to the latest version of Ubuntu. Is it possible? I read on this forum that I have to do a serial upgrading. If that is  the case, will all my software installed  previously be safe or do I have to reinstall them again? what happens to my data after upgrading?

What are the different ways I can use to upgrade Ubuntu from one release to another?

Why is it that Ubuntu only support a version for a limited time? Since I have been on this site I have seen many references to particular versions not being supported. What does it actually mean? After this time must a user just use the OS in the state it is in at the date that support ends? Does this mean no more package updates are available?   Or when this support date has elapsed, should the user then abandon the version and install a newer version instead? I am slightly confused with the difference between Ubuntu and Linux here (with Windows you use it until you buy the latest version) and would be grateful if someone could explain the Ubuntu 'lifecycle' (if that is a suitable word). Thanks in advance for your help.

I am currently using Ubuntu 12.04.2 32bit. I installed it using LiveCD.  Tomorrow, 23rd August 2013,Ubuntu 12.04.3 is released. I want to upgrade from Ubuntu 12.04.2 to Ubuntu 12.04.3 without using any LiveCD. Is it possible? If so please suggest me how can I do.  Actually while using Ubuntu 12.04.2 I have troubled with graphics. My graphics card is Intel i845G 64 MB. When Ubuntu starts it works fine and smooth without any lagging, but after sometime it hangs for few seconds (1 or 2 seconds) with a garbage screen and becomes sluggish. All windows and browsers start lagging and also it is not possible to play any video in any player (VLC, Movie Player, Xnoise, SMPlayer etc..).  I think Upgrading to Ubuntu 12.04.3 could fix my problem.  Any help will be greatly appreciated..    I've posted an answer to upgrade Ubuntu 12.04.x to 12.04.4.

I answered  about do-release-upgrade not allowing an upgrade of 14.10 to 15.04 only to 15.10, I assumed it was due to 15.04 being end of life.  A user (@xangua ) posted that it was not possible to skip a release with do-release-upgrade, so I looked in to this information by running the command on my 14.04 box, but this is where the confusion began.  My 14.04 wants to upgrade straight to 15.04?   Of course this invalidates my answer as 15.04 is end of life, but why does this command seem to be skipping versions, if not based on end of life?   There is no indication any thing from 14.10 is being downloaded by the upgrade and software-updater says Ubuntu 15.04 is now available for download, some clarification of this would be great.

How can I switch on the option to be notified for a new Ubuntu version, which you usually find in      Dash --> System Settings --> Software &amp; Updates --> Updates --> Notify me of a new Ubuntu version`   from command line to never?

I had several friends ask me to update their Ubuntu to a newer kernel without changing the version of Ubuntu. So for example, staying in 10.04 with the 3.3 Kernel version.  When having an older or present Ubuntu version, many users want to apply the newer stable/unstable kernel version to the Ubuntu version they are using thinking that it is similar to upgrading a program. So what I am looking for, are some simple answers to explain the dangers (that are pretty much bigger than the advantages) of forcing a newer kernel version in a Ubuntu release that was not meant for it.  What can I tell them or explain to them of why they should NOT update to a newer/older kernel when having an Ubuntu version that was not made for that kernel version.

I upgraded from 18.04 to 19.10 some months ago and now I want to upgrade to 20.04. But update-manager -c doesn't show the new Ubuntu release 20.04.  Isn't the upgrade ready yet? Is it possible to upgrade to 20.04 from 19.10 now?

Yesterday I upgraded my Ubuntu Desktop from LTS 14.04 to LTS 16.04. I did it via Software Updater.  There were several errors during the upgrade (is there a place where these errors are listed in the system so I can post it here?). The last one of them was at the end, saying that the boot partition was full. Following a post, I deleted a few kernels which I thought were old.  Now when I do uname -r it tells me that the kernel version is 3.13.0-93-generic, but it should be 4.4 something right? Can it be that I deleted the correct kernel by mistake? If yes, how do I fix this?  But the command cat /etc/os-release shows:  NAME="Ubuntu" VERSION="16.04.1 LTS (Xenial Xerus)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 16.04.1 LTS" VERSION_ID="16.04" HOME_URL="http://www.ubuntu.com/" SUPPORT_URL="http://help.ubuntu.com/" BUG_REPORT_URL="http://bugs.launchpad.net/ubuntu/" UBUNTU_CODENAME=xenial   The system seems to think it is 16.04 but I have a feeling there are many other wrong things, I just don't know how to find these upgrade errors.  Is there an official ubuntu post upgrade script that checks if everything is ok?  I don't know if it adds anything, but two other errors that I remember were that the ubuntu software center did not work after the upgrade, I fixed following a post that said it had something to do with a language setting. The other error was that on boot it showed "Lvmetad is not active yet, using direct activation during sysinit" which I fixed by edditing the GRUB file.  Anyways, I just want to know if my system is ok and what is the meaning of this contradiction between the kernel and the system version (if 16.04 had the wrong kernel would it even boot?)  Thank you very much in advance for any help!!!  Edit: Here is what I have installed (output of dpkg -l | grep linux-image):  linux-image-3.11.0-19-generic                                                                linux-image-3.11.0-20-generic                                                                linux-image-3.11.0-22-generic                                                               linux-image-3.13.0-93-generic                                                               linux-image-extra-3.11.0-19-generic                                                           linux-image-extra-3.11.0-20-generic                                                           linux-image-extra-3.11.0-22-generic                                                        linux-image-extra-3.13.0-93-generic

I have an Asus K55V and I'm wondering which version of Ubuntu I should be attempting to use. The website offers 12.04 (LTS) and 12.10.

When I upgrade from one version of Ubuntu to the next, the upgrade tool rightly disables all my PPAs, so that software compiled for or otherwise tied to the old version of Ubuntu does not interfere with the new version that I just upgraded to.  Is there any way to automatically re-enable and update any PPAs that provide packages for the new version of Ubuntu? For example, suppose I'm currently running Maverick, and I have two PPAs enabled, "foo" and "bar". Suppose that "foo" provides packages for both Maverick and Natty, while "bar" provides packages for Natty only. Is there a tool I could run after updating to Natty that would re-enable my "foo" PPA and update it to point to the Natty packages, while leaving the "bar" PPA disabled?

Question is about Ubuntu release process. Are migrations from n to n+1 releases expected?  Assuming we have server with installed Ubuntu 14.04 LTS. Will it be smoothly upgradable to Ubuntu 16.04 LTS via apt-get upgrade ?  Assumptions:   scope is software therefore we assume that given hardware is supported on both releases (upgrading from and to) that's why, always before upgrade you are asked to make backup to be able to revert in case of failure

Currently I'm running Linux-3.0 and I want to update it to Linux-3.3.1 the latest stable kernel release as mentioned at . Can I update to 3.3.1 in Ubuntu without any risk of crashes? I'm updating my kernel regularly as provided by the Update Manager..Currently I have Linux-3.0.0.17..Can I update?  NOTE:  The latest kernel version any user is supposed to use in Ubuntu is updated automatically via the Update Manager, so no action is normally required by user regarding kernel upgrades. What the question author is referring to is mainline kernel, see:

^^^^ 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?

I am going to change my machine: from a laptop with Ubuntu to another laptop where I am going to install Ubuntu...  I am quite happy with the current system, what I am afraid of is having to rebuild everything from 0.  So what do people often do to clone an Ubuntu system? That may include the data, packages, shortcut settings, etc...
