Currently I'm using Ubuntu 12.04. I would like to upgrade to 14.04. Should I backup  some important such as those of the web root folder ? If I would need so,  how should I proceed ?

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

I was under the impression that upgrading to Ubuntu 14.04 was supported from all version between and including the previous LTS release (12.04). Why is it then, that update-manager (with and without -d option) will only offer to upgrade to version 13.10 from my Ubuntu 12.10 system? Even that only works when I change the updater settings from "For long-term support versions" to "For any new version."  Is it only possible to upgrade to 14.04 via 13.10?

When I attempt to upgrade Ubuntu from 17.10 to 18.04, the Update Manger says "Your computer is up-to-date."  Why isn't it detecting the new release?

Upon my observation, seems new packages will first appear in security.ubuntu.com, but if you upgrade later, they will appear in XX.archive.ubuntu.com (depends on your config),  Was that true ?

How do I install the latest  on Ubuntu? I've been looking around, and I can't find anything. Is there a Ubuntu package for node.js, or do I have to compile it myself?

I've upgraded my LTS version of Ubuntu to Ubuntu 17.04 and from the day I've upgraded I've been struggling to get this thing stable. Sometimes my Wifi adapter doesn't work properly and sometimes I can't even copy things properly.  So I want to revert back to Ubuntu 16.04 LTS.  Is there any way to get this done?

I want to use do-release-upgrade to upgrade from 18.04 to 20.04, but I can't do that do-release-upgrade Checking for a new Ubuntu release There is no development version of an LTS available.  It seems that  is used, and it still points to 18.04. Do you know when (or how?) can I upgrade to 20.04?

I'm on an old Ubuntu version (Ubuntu 6.06.2 LTS Server) which isn't really supported any more. So the automatic updates don't work. I have ISPConfig installed to manage a few web sites.  What's the best course of action? I'd like to upgrade to something current, but I can't figure out how to go about doing this, given that the apt-get scripts don't really work any longer.

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?

On a Lenovo laptop, I want to upgrade from Ubuntu 18.04 to Ubuntu 18.10 (budgie).  When I select upgrade on the update manager, the dialog box disappears and nothing happens. The upgrade doesn't start.  Note- I went through the same procedure this morning on my other laptop and Ubuntu successfully upgraded.   do-release-upgrade fails to upgrade and throws this error:  Please install all available updates for your release before upgrading.   What can I do to upgrade the system successfully?

I am trying to install current stable version 0.12.1, but it only installs 0.9.9. Any chance to install latest version with apt-get install? It seems that 0.9.9 is very old :(

I'm using Ubuntu 12.04 on my computer and I want to upgrade to Ubuntu 14.04.  I do not have internet at home, so I need to do the upgrade offline.  On openSUSE there a way to make the upgrade offline simple and effective way is by using  the iso DVD.  My question is: Is there any way to make Ubuntu upgrade offline as in openSUSE ?

I'm fighting the 'too small /boot partition' problem, and it looks like I'm going to have to either re-partition or install a larger drive (AND re-partition?). I keep seeing warnings that I should be sure to "back up important files," but excuse my ignorance -- what are "important files"? Incidentally, I have about $200 worth of Ubuntu books that don't explain this, or even what to back up when you back up. Sigh.  Specifically:   Back up the /home directory. However, without using sudo, this fails to backup about five files (for example, a 'lock' file). Am I ok, or do I need to use sudo? I suspect I should back up /etc. With sudo? Where are the files for things like games and apps? Do I need to back them up? If I'm doing a "clean install," is there any point to backing up the whole frickin' drive? If I'm going to repartition /boot, what should I back up before I do that? If I back up the drive, repartition, and then restore the backup, will it "restore" the old /boot partition?   Inquiring minds are flummoxed.

Yesterday I started the upgrade from 12.10 to 13.04, but I interrupted it because it was taking too long. Now if I restart it, it doesn't proceed.  Is there any possibility to clean the mess it left when I interrupted it and make a clean restart of this update?

How can I safely upgrade an Ubuntu installation from one release to another? What should I do before upgrading to ensure it goes smoothly, and is there any clean-up I need to do afterwards?  In particular, do I need to do anything special if I am using packages from PPAs, if I have a graphics card that needs drivers, or if I'm running a custom Linux kernel?  This is a general question , but as example we take Ubuntu 12.04 and Ubuntu 12.10
