Sounds like you are using old version of Traccar. Use latest one.
I used wget https://github.com/traccar/traccar/releases/download/v3.16/traccar-linux-3.16.zip
what is the latest version - how to find out?
Are you serious? Click on the "Download" button on the top of this page.
Yes, that's the latest one
I am getting the above error when running: ./traccar.run
java -version
-> 11.0.3
which java
/usr/bin/java
Been trying few suggestions from the forum, but still no luck
