[ Solved ]: Cannot find version 14 of OpenJDK for Ubuntu 20.04

  • 772

As of today (May 6th, 2020), the problem described below is now obsolate, because OpenJDK-14 has finally appeared in Ubuntu 20.04 repository.

I've installed Ubuntu 20.04 Focal Fossa and was trying to install the latest Java JDKs in both flavours: OpenJDK and Oracle. However, searching via apt search gives OpenJDK (and also JRE) only up to 11th edition.

Searching on https://packages.ubuntu.com/ narrowed to focal distribution also gives results up to openjdk-11-jXX. Switching the distribution of choice to eoan, gives all up to date versions including 14th.

I'm not asking how to enforce the installation of exactly 14th edition of OpenJDK, but rather for the reason for this? Is it due to any security reasons and I should also get rid of 14th Oracle version (downgrade it to 11th)? Or just patiently wait because OpenJDK-14 need to be approved for Focal Fossa?

jdk openjdk 20.04

    I believe it is simply not done yet. If you go to "Software & Updates" and enable "Developer Options" / "Pre-released updated (focal-proposed)", the package shows up.

    Here's what I did to get the package:

    • Checked the checkbox
    • sudo apt update
    • (ignore all the other proposed updates)
    • sudo apt install openjdk-14-jdk
    • Unchecked the checkbox
    • sudo apt update
    • (observer that the other proposed updates are now gone)

    I don't know if that is a good recommendation, but it worked for me to get a java-14 installation on my machine :)
