Alright, thank you for the swift reply! Will message the admin then.

Hi there,

I wish to delete my account. How do I achieve that? There doesn't seem to be any option in the account preferences menu.

You don't need to apologize, I'm glad you took the time to explain what was at fault here. Thank you for your help and your insights!

I guess I'm not the only one running into this issue for as long as the client remains on java 15. Could you reach out to those responsible for the linux guide? Maybe they could add a paragraph about potential issues with divergent java editions instead of a plain "the client wont work with different versions".

@nathmate said in Can't install on Ubuntu 20.04: missing Java 15:

I moved away from Ubuntu pretty quickly because the PPA system never worked very well for me.

You could just untar this somewhere and point the client to it. https://jdk.java.net/15/

Thanks for the advice. I've downloaded the archive and extracted the contents to /usr/lib/jvm. Afterwards I issued the "INSTALL4J_JAVA_HOME" command and pointed towards the folder. When checking the version with "java -version", it stills says I'm running java 16.

However, starting the FAF client in the terminal after linking the appropriate java folder suddenly works!

@nathmate

Thanks for the advice, but as I said the problem isn't that the client isn't correctly pointed to the correct java install, but rather the fact that I can't install java 15, for there isn't any suitable installer found in the repositories.

For instance if I try to install java 15 (doesn't matter if oracle or open), I always get forwarded to the newer release. The client however insists on the outdated version 15, and refuses to start with a newer implementation.

Install the openjdk-15-jre package instead.

Same problem as with the oracle one, Openjdk isn't available anymore:

"Note, selecting 'oracle-java16-installer' instead of 'openjdk-15-jre'"

For quite some time Java is open source und the OpenJDK project. Oracle is no longer the only company publishing a compiled binary of the Java Development Kit / Runtime Environment.
AdoptOpenJDK is one of many alternative binaries.

Thank you for your insights, the wiki however states the following (article about setting up faf on linux, figure 5):

"Note: The client doesn't work with other Java versions."

I've tried with various Java implements, they all fail to work with faf's client. Here's what it says when trying to run the client by console prompt:

"No suitable Java Virtual Machine could be found on your system.
The version of the JVM must be 15.
Please define INSTALL4J_JAVA_HOME to point to a suitable JVM."

Did you try it with adoptopenjdk 15?

Never heard of it. Would you elaborate?

Hi there,

I tried to install the java FAF-Client, but the package oracle-java15-installer is no longer available in the ppa.
Installed Java 16 instead, but the launcher insists on using Java 15.

any ideas how to solve this?
