I am running latest Kubuntu 20.04 with dolphin file manager version 19.12.3. However the latest stable version is already available as 20.04.3  Therefore, I am wondering if the release cycle is different as officially I couldn't download it and latest available version is still locked to the older version of 19.12.3  I realised that i could possibly simply fetch the latest version from flatpak as well  However, I am interested to know why it was not available to download officially. Also, I would like to know the lifecycle of latest stable version of KDE packages to be released for Kubuntu/Ubuntu repository and when would it be available to download officially? Thank you

Why are packages in the official Ubuntu repositories older than the latest (upstream) versions from Debian Sid, PPAs, the authors, etc.?

I'm running several Ubuntu 18.04 machines all of which need OpenSSL.  Recently, OpenSSL reported a security problem:  (CVE-2020-1967).  I did install OpenSSL via the Ubuntu standard packages, no custom package sources here nor did I compile it myself. So, since this is the case and since I'm using a currently maintained LTS distribution (18.04 as mentioned), I assumed that running apt update and apt upgrade would be sufficient to get the latest updates and be safe from that vulnerability. But, no. Obviously, it is more complicated.  According to  there is an OpenSSL package version for Ubuntu which reacts to the aforementioned CVE-2020-1967. However, it still contains 1.1.1f in its version name, whereas the OpenSSL version where the problem is fixed is actually 1.1.1g (according to their advice). And, more important: That package is only for Focal Fossa (20.04).  So, I thought I take the chance to learn a few things about the internals of Ubuntu and how package version make their way to my computer:   How come that new packages are only created for newer LTS distributions and older ones are left vulnerable? How does that process work in general? What is the average time between a vulnerability being publicly announced and patched packages being available via apt upgrade?

I would like to upgrade my main system to 16.04, but I work on projects that require OpenJDK 7.   Apparently it is not available from a trivial apt-get install openjdk-7-jdk. Only versions 8 and 9 are listed in the repository.  Can anyone point me to instructions on how to install it?

I have read a lot of threads with similar questions, but after reading the answers, I am very confused. I have found in them lots of url's with repositories but people discusses about which repositories are made for one or two versions of ubuntu, but I have found nothing about 11.10 version. Is too soon to ask for that? Should I downgrade my ubuntu to have a realtime kernel?

I'd love to test the latest Ubuntu alpha/beta (otherwise known as "Ubuntu+1"), but I can't find it.   Where can I find download for the pre-releases of Ubuntu?

I'm running the current stable Ubuntu version (Oneiric) but have issues with the shipped kernel. Newer kernel versions seem to have fixed it, but the kernel-ppa/ppa does not contain the most recent kernel which is why I want to install the kernel from the next stable version (Precise). Since I want to be able to unload out of tree kernel modules, the mainline kernel from  cannot be used.  I also have have Virtual Box installed which also need to work in the new kernel so the "kernel headers" have to be upgraded as well.  How am I supposed to install the kernel packages from the next stable version (Precise) without upgrading all other packages?

Lately whenever I run software update I get the message    suggesting that my version of Ubuntu is EOL. But when I run lsb_release -a I get  No LSB modules are available. Distributor ID: Ubuntu Description:    Ubuntu 14.04.5 LTS Release:    14.04 Codename:   trusty   Which of these numbers should I pay attention to? 14.04 or 14.04.5? Because according to the  support for 14.04.5 runs out on April 2019.

When I open Ubuntu Software, and check the installed software, I found that there are 2 different versions of GNOME runtime (3.26 and 3.28).   How to check which one of them is running? Is it OK to uninstall one of them (the one that is not used)?  INFO:  I am using Ubuntu 18.04 gnome-shell --version gives: GNOME Shell 3.28.4

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.

LibreOffice is seeing some dramatic improvements each version and subversion that goes out.   I would like to have always the latest version of LibreOffice on my machine(s). I know of the PPA that exists but is it recommended to use it with 12.04 for daily use? What are the pro and cons of using the PPA? Will it break my system/Libreoffice installation?  Does libreoffice get eventually also upgraded in the Ubuntu repositories or does this upgrade happen only with new releases? Who manages the upgrades of libreoffice in Ubuntu and in the PPA?

I need to install libesd0-dev, but while it is available on earlier versions of Ubuntu from apt-get, it's not available for 18.04. Is there still a way for me to install it, or do I have to downgrade?

Where can I get the old repositories for Ubuntu versions? In my case, it's 9.04 Jaunty?   I found all the official repositories and their mirrors have been removed. I am wondering where I can get the repository list for this version?

I want the very latest version of Python, but I don't want to bypass the apt package manager: I don't want to do an old-school source install because that can make it harder to uninstall when the official packages come out.  Python3.5 is not currently featured in any of Canonical's package repositories, which means I cannot just "apt-get install python3.5".  Is there a way to get Python3.5 installed on my PC in the meantime?

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 am aware that similar questions have been answered before for different versions/releases of Ubuntu, but I cannot find an application to reformat a USB stick in Kubuntu 12.04.01. Right-clicking the drive in Dolphin doesn't give the format option. Is it possible on software that comes with the package, without resorting to the Terminal or GParted?
