traccar.run command not found

I now have a new VPS server and I need some advice.

When I run the install program tracer.run, I am getting errors:

./traccarbin/traccar.run

As this is the first time I have used an unmanaged VPS host, there is probably something I have not done.

Please can you suggest some next steps to resolve the issue.

Many thanks

Looks like you are missing Java, or it's misconfigured.

Thanks for the advice Anton !

Anton was correct. When I deleted Java and reloaded it using rpm the software worked first time.
Many thanks
