The following 1 profile is active: "install"

ThingsBoard Edge installation failed!

I use the Debian release located here with OpenJDK 17.0.2. My guess is that I've missed something obvious, but I have no experience working with Java and have a hard time troubleshooting this on my own, any guess on what I might have missed?

Environment

• OS: Poky Scarthgap
• ThingsBoard: 3.8

Hello, I’ll try to help you :)

First of all, it’s important to mention that Edge depends on ThingsBoard Community Edition, so it’s essential to have ThingsBoard Community Edition installed. Alternatively, you can use our demo.

You will need to register (or log in with your email).

Next, the following guide will help you: Edge-instruction.

The link you provided is for ThingsBoard Community Edition.

Therefore, if you are specifically interested in Edge, please follow all the steps in the guide I provided, and everything will work :)

If you have any questions, feel free to ask. I’ll be happy to assist you!

Thanks for the help!

I noticed that I've forgotten the Community Edition, however the same error shows up when I try to run install.sh as part of the installation process for the Community Edition. I follow this https://thingsboard.io/docs/user-guide/install/ubuntu/ but on my system update-alternatives might work differently, what is expected of update-alternatives and what is the error a symptom of?

[jekka001]

The command sudo update-alternatives --config java is used to select the desired Java version, in this case, Java 17, which will be set as the default on your system.
When you run this command, it will display a list of available Java versions. You may see something like this:

Selection    Path                                      Priority   Status
------------------------------------------------------------
* 0            /usr/lib/jvm/java-11-openjdk-amd64/bin/java  1111      auto mode
 1            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java  1081      manual mode
 2            /usr/lib/jvm/java-11-openjdk-amd64/bin/java  1111      manual mode
 3            /usr/lib/jvm/java-17-openjdk-amd64/bin/java  1711      manual mode

In this case, you should enter 3 because Java 17 is listed as option 3.

If everything is done correctly, running the command java -version should display the following output:

openjdk version "17.x.xx" 
OpenJDK Runtime Environment (...)
OpenJDK 64-Bit Server VM (...)

If you encounter any issues, please provide as much information as possible, including logs after running these commands, so I can assist you further.
