Is it possible to install openjdk-8-jre-headless on RPi4?

Is it possible to install openjdk-8-jre-headless on RPi4?
I need it to install the unifi controller, and I prefer not to use docker.

2

Why not try it? I imagine it will work.

3

In the official repositories there is only version 11, openjdk-11-jdk-headless, which does not work with the unifi controller.
Is it possible to add some old repository, debian, raspbian?

4

I would like to install the unifi controller also on my vero but im only familiar with relative simple installs. So a step by step guide would be cool ,if someone knows how to do this. Tom

Hi,

Looks like it should work with docker:

Thanks Tom.

6

Is this the same for vero?
So every sudo is a new command Line i should type in SSH?

7

Hi,

I canā€™t see why not

All the lines except change IDs (this are the edits) need to be run.

Thanks Tom.

8

Could you simplify this text a bit? So what i need to give in SSH as command. If its not to much Troubleā€¦ Im still learning to use the command Line. Thanks in advance

Hi,

Not really, its list of commands that need to be run. This should help:

Thanks Tom.

10

Ok i understand but i mean could you delete the lines of the id in the text above. Because i dont know exactly where to start and finish the chance of linesšŸ™ƒ

11

Hi,

Change id= are changes to /etc/os-release. You need to find the line in that file and update as advised.

Thanks Tom.

Hi,

Just tried to set this up on my test vero4k. Slight change in instructions, so please revert any previous changes and try this:

sudo update-alternatives --set iptables /usr/sbin/iptables-legacy

Then follow the instructions for installing docker from here:

Then finish the unifi installation with:

sudo usermod -aG docker $USER
sudo apt install docker-compose
sudo reboot 0
mkdir unifi && cd unifi
curl -O https://raw.githubusercontent.com/ryansch/docker-unifi-rpi/master/docker-compose.yml
sudo docker-compose up -d

Thanks Tom.
