Can not build image: Package 'openjdk-7-jdk' has no installation candidate

[koocotte]

It looks like the openjdk-7 for ubuntu xenial is no more available in the selected PPA.

Browsing http://ppa.launchpad.net/openjdk-r/ppa/ubuntu/dists/xenial/main/binary-amd64/ show that the Packages.gz have been updated on 2021-04-21 and there is (no more?) references to a jdk older than openjdk-9

There are .deb in http://ppa.launchpad.net/openjdk-r/ppa/ubuntu/pool/main/o/openjdk-7/ but probably only for Lucid Lynx.

Package openjdk-7-jdk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

It's quite possible that it's just not supported anymore.

I will test iDRAC with the newer Java versions and see if it works, otherwise I have to find a new source for OpenJDK 7. Will probably have some time to do this next week.

[DomiStyle]

I looked into it now and it seems like OpenJDK 7 is gone from all the repos for modern OS (obviously). There are some for older OS but I don't have a baseimage for them.

Looks like the only way around is downloading the JDK from Oracle, which I probably am not allowed to bundle with this image, or building Java by myself.

I run the Alpine Linux version using the repo from pull request #9 and it looks like Java is found and working.

My french keyboard is not working as expected (mapping does not correspond neither to english nor french, maybe a double decode of mapping), but it's another problem. I see you have patchs about keyboard in the last release. I must check if I can merge both.

[DomiStyle]

Interesting. You're right, Alpine still has openjdk7 packages: https://pkgs.alpinelinux.org/packages?name=openjdk7*&branch=edge

I will check if I can get the keycode hack to compile on Alpine.

[DomiStyle]

It looks like Alpine still has the same issues for which I didn't accept the pull request in the first place:

• Native libraries can't be loaded because of issues with libmawt.so
• Opening Virtual media crashes container

Zulu Java is the only openjdk distribution that is still packaging Java 7: https://www.azul.com/downloads/?package=jdk

I had a branch where I tried switching to it, but the build fails because you also need to install the libx11-dev in order to compile the keycode-hack. Once I got past that, I still ran in to issue #17 so I gave up on that branch.

Supposedly, you can get iDrac 6 working with Java 8 by modifying the allowed tls algorithms.

[DomiStyle]

@kusol Thanks, I will check if I can get things working with Java 8 in Ubuntu and switch to the Zulu Java builds if that doesn't work.

@kusold does this solve your issue https://github.com/DomiStyle/docker-idrac6/pull/47 ?
