Will OpenJDK 15 be available in Ubuntu 20.04 LTS?

Asked by John Neffenger on 2020-10-20

Will the OpenJDK 15 packages eventually be made available in Ubuntu 20.04 LTS? Or will we need to upgrade to Ubuntu 20.10 to get OpenJDK 15?

The OpenJDK-Updates Wiki page (https://wiki.ubuntu.com/OpenJDK-Updates) makes me think these short-term OpenJDK releases will be available in the Ubuntu LTS releases, but if so, I'm curious when that will happen.

Thank you,
John

This is not answering your question, but there is already a PPA with openjdk-15 for Ubuntu focal,
https://launchpad.net/~openjdk-r/+archive/ubuntu/ppa

You would have to Upgrade to Ubuntu 20.10 Groovy It is one of its packages. https://packages.ubuntu.com/groovy/openjdk-15-jre
The Official Release of Ubuntu 20.10 is 2020-10-22 . Otherwise you would be installing the beta version.

Just to clarify: I thought the point of the stable release exception for OpenJDK (https://wiki.ubuntu.com/StableReleaseUpdates#openjdk-N) was so that the older of the two OpenJDK short-term support releases in the updates pocket could be removed and replaced with the most recent release every six months. For example, the current OpenJDK 13 and 14 in Ubuntu 20.04 would be replaced by OpenJDK 14 and 15 this fall, and then those two by OpenJDK 15 and 16 next spring, and so on.

Meanwhile, the OpenJDK LTS releases (8 and 11) would remain in the release pocket of Ubuntu 20.04.

Did I misunderstand the meaning of the stable release exception?

Thanks,
John

One thing to consider is Ubuntu 20.04 Focal is derived from Debian - Buster Ubuntu 20.10 Groovy is derived from Debian - Bullseye
https://wiki.ubuntu.com/OpenJDK-Updates
openjdk-15 package in Ubuntu
openjdk-15-dbg: No summary available for openjdk-15-dbg in ubuntu focal.
openjdk-15-jdk: No summary available for openjdk-15-jdk in ubuntu focal.
openjdk-15-jre: No summary available for openjdk-15-jre in ubuntu focal.

My interpretation of https://wiki.ubuntu.com/OpenJDK-Updates and https://wiki.ubuntu.com/StableReleaseUpdates#openjdk-N is similar to yours. In my opinion openjdk-15 should be made available in the focal-updates repositories.

But Bug #1871161 tells something different.

Remark: in https://launchpad.net/ubuntu/+source/openjdk-15/+publishinghistory you can see that in spring 2020 openjdk-15 was available in focal-proposed, but never made it into focal-updates (and meanwhile has been removed again).

yes, the intent was to update these. I'll need to find some time ...

Thank you for your comments, Matthias, Manfred, and Bernard.

Regarding the "PPA for OpenJDK uploads (restricted)" (https://launchpad.net/~openjdk-r/+archive/ubuntu/ppa) ...

I have always avoided adding PPAs on my system because of the warning about installing "unsupported packages from this untrusted PPA." Yet, if packages from this PPA are built (a) by the same people who build the official OpenJDK packages for Ubuntu, and (b) on the same Launchpad Build Farm that builds the official packages, they should be completely safe except for perhaps some versioning conflicts. Is that right? Would adding these packages to the backports pocket be easier and faster than getting them into the updates pocket?

Meanwhile, I created Snap packages of the latest general-availability release and early-access builds of OpenJDK for all six architectures (https://snapcraft.io/openjdk), just as another option.

Can you help with this problem?
