Right, there's your problem - all the files are owned by root instead of your user pi. I suspect that it might be the same for the tracker directory - can you confirm (e.g. by running ls -l /home/pi | grep tracker)? You should change the owner and group to whatever they should be ( pi for the user and whatever group its files are usually in - check other files in the home directory to see). You can do that with chown (e.g. chown -R user:group /home/pi/tracker, but see the man page or other docs as I'm not at a Linux machine right now) and you will need to use sudo to do so.

[corsasri]

Typed ls -l /home/pi | grep tracker

pi@raspberrypi:~ $ ls -l /home/pi | grep tracker
drwxr-xr-x 3 root root 4096 Jul 16 09:09 mytracker
drwxr-xr-x 4 root root 4096 Jul 15 20:31 tracker
pi@raspberrypi:~ $

Then this and then added sudo but think i done it wrong.

pi@raspberrypi:~ $ chown -R user:group /home/pi/tracker
chown: invalid user: ‘user:group’
pi@raspberrypi:~ $ sudo chown -R user:group /home/pi/tracker
chown: invalid user: ‘user:group’
pi@raspberrypi:~ $

[ndc85430]

You need to specify the actual user and group, i.e. pi and whatever the group should be (which is why I suggested you check).

Perhaps you should also read about permissions in Linux, e.g. here.

[corsasri]

Sorry but i dont understand. Yes my user name is pi, and what is the group ? I want to grant all the files in the tracker folder. so can you show an eexample if possable.
Sorry again im new to all of this.

[ndc85430]

Check the other files in /home/pi to see which group is set (again just by doing ls -l in that directory). See the link in my last post as well, it covers quite a bit of useful stuff.

[corsasri]

It looks like there pi.

Yes. Now you can run chown if you haven't already.

[corsasri]

Still not right.

I mean, the command is the same as I gave you in a previous post, just you need to set the user and group, which you now know.
