I've found the solution.

I needed to start JLinkExe before running JLinkRTTClient.

First I call JLinkExe -device NRF52832_XXAA -if SWD -speed 12000 -autoconnect 1

Then I connect using JLinkRTTClient and I can now view the debug output.

I also removed app_trace_init from my code as this doesn't seem to be necessary in my case.

Thanks James. The tutorial uses the RTT viewer which doesn't yet exist on Linux if I've understood correctly. I did find the solution which I'll indicate below.

Please try to follow the RTT Debugging tutorial here: devzone.nordicsemi.com/.../

Using the RTT Viewer you have the ability to log all data on channel 1 into a file.

It's working well for me.
