[Solved] Unifi controller

Hi,

I have had a lot of issues with the Unifi controller from AUR. I tried to install it, but it crashes all the time. Does anybody know a way to get installed? It would be a shame to ditch Arch Linux just for this very important package.

Thanks,

Alexander

Re: [Solved] Unifi controller

unifi needs java-runtime-headless<9 and java-runtime-headless>=8 which means it needs java-runtime-headless=8

Re: [Solved] Unifi controller

https://wiki.archlinux.org/index.php/Ja … va_version

I think unifi needs java 8, so the service file should probably be changed like this:

Environment="PATH=/usr/lib/jvm/java-8-openjdk/jre/bin:/usr/local/bin:/usr/bin"
ExecStart=/usr/lib/jvm/java-8-openjdk/jre/bin/java -jar /usr/lib/unifi/lib/ace.jar start
ExecStop=/usr/lib/jvm/java-8-openjdk/jre/bin/java -jar /usr/lib/unifi/lib/ace.jar stop

There is also the docker image as a last alternative.

Re: [Solved] Unifi controller

Hi guys,

Thank you very much, this was very helpful! The problem was the Java version. I just installed the default version. After I installed Java 8. It worked perfectly.

Regards,

Alexander
