traccar 6.4 on rpi 64bit

And which installer did you download?

Oh. Ok. Noted on the Google Map API key license now. Sorry I was ignorant earlier thinking it was free ... :)

traccar-linux-arm-6.4.zip

That should work.

Not sure if this is still a java version issue.

pi@home-server:~ $ java -version
openjdk version "17.0.12" 2024-07-16
OpenJDK Runtime Environment (build 17.0.12+7-Raspbian-2deb11u1rpt1)
OpenJDK Client VM (build 17.0.12+7-Raspbian-2deb11u1rpt1, mixed mode, emulated-client)
pi@home-server:~ $

I have completely uninstalled traccar:
Stop systemd service
sudo systemctl stop traccar
Remove systemd service
sudo systemctl disable traccar
sudo rm /etc/systemd/system/traccar.service
sudo systemctl daemon-reload
Remove traccar directory
sudo rm -R /opt/traccar

Then re-installed:
sudo ./traccar.run
sudo systemctl start traccar

But I get this error:

bristol406 do this:

cd /opt/traccar
/opt/traccar/jre/bin/java -jar tracker-server.jar conf/traccar.xml

pi@home-server:/opt/traccar $
 /opt/traccar/jre/bin/java -jar tracker-server.jar conf/traccar.xml
-bash: /opt/traccar/jre/bin/java: No such file or directory
pi@home-server:/opt/traccar $

But there is such file, right? You need to check why your OS doesn't think there's a file. Possibly permissions issue or something. Also you have to run it as root.

Then it means traccar is not installed.

Is this not the installation ?

pi@home-server:/opt/traccar $ ls
conf  data  jre  lib  logs  schema  templates  tracker-server.jar  web
pi@home-server:/opt/traccar $

I thought that traccar automatically ran as root. If it doesn't how do I force it ?

We're talking about running the command manually.

pi@home-server:/opt/traccar $ sudo /opt/traccar/jre/bin/java -jar tracker-server.jar conf/traccar.xml
sudo: unable to execute /opt/traccar/jre/bin/java: No such file or directory
pi@home-server:/opt/traccar $

I guess it must be permissions issue but it was jus a standard installation

ls -al /opt/traccar/jre/bin/java ??
