How to install latest stable dolphin file manager on Kubuntu via xdg-open(Discover)?

rated 0 times [ 5] [ 0] / answers: 1 / hits: 1994 / 2 Years ago, fri, march 18, 2022, 12:15:52

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 https://kde.org/applications/en/system/org.kde.dolphin

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 https://pkgs.org/download/dolphin

I realised that i could possibly simply fetch the latest version from flatpak as well https://flathub.org/apps/details/org.kde.dolphin

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

Here's how to find out for yourself:

You can find the correct version for your release of Ubuntu (including Kubuntu, of course), using the madison search feature in the apt-cache application.
```
  $ apt-cache madison dolphin

dolphin | 4:19.12.3-0ubuntu1 | http://us.archive.ubuntu.com/ubuntu focal/universe amd64 Packages
```
The correct version of dolphin in 20.04 (Focal) is 19.12.3-0ubuntu1

You can find the correct version for ALL supported releases of Ubuntu using the rmadison command, provided by the devscripts package.

$ rmadison dolphin

dolphin | 4:4.8.2-0ubuntu2    | precise                 | amd64, armel, armhf, i386, powerpc

dolphin | 4:4.8.5-0ubuntu0.1  | precise-updates         | amd64, armel, armhf, i386, powerpc

dolphin | 4:4.13.0-0ubuntu1   | trusty/universe         | amd64, arm64, armhf, i386, powerpc, ppc64el

dolphin | 4:4.13.3-0ubuntu0.1 | trusty-updates/universe | amd64, arm64, armhf, i386, powerpc, ppc64el

dolphin | 4:15.12.3-0ubuntu1  | xenial/universe         | source, amd64, arm64, armhf, i386, powerpc, ppc64el, s390x

dolphin | 4:17.12.3-0ubuntu1  | bionic/universe         | source, amd64, arm64, armhf, i386, ppc64el, s390x

dolphin | 4:19.04.3-0ubuntu1  | eoan/universe           | source, amd64, arm64, armhf, i386, ppc64el, s390x

dolphin | 4:19.12.3-0ubuntu1  | focal/universe          | source, amd64, arm64, armhf, ppc64el, riscv64, s390x

dolphin | 4:20.04.3-0ubuntu1  | groovy/universe         | source, amd64, arm64, armhf, ppc64el, riscv64, s390x

Dolphin 20.04.3 is not available in Ubuntu 20.04 (Focal). It's available in Ubuntu 20.10 (Groovy), which is scheduled for release in October 2020 and is currently in pre-release testing.

Most users should NOT be trying to manually download and install new versions. You risk breaking your system, and you will get those upgrades with the next release of Ubuntu anyway. That's one reason Ubuntu does interim releases every six months.

You are welcome to become a 20.10 tester, of course. We can always use more folks willing to test, troubleshoot, and file good bug reports on the problem that they discover in new software.
