[PROBLEM] how do I access the log?

[Tim Curtis]

The first log to check is the Moode startup log right after rebooting.

Code:

moodeutl -l

Then maybe the dmesg log but its very technical and typically is only useful for identifying certain types of hardware failures.

Code:

dmesg

Sometimes syslog contains a telltale but usually its just filled with all sorts of log records that look ominous but are in fact harmless.

Code:

cat /var/log/syslog

You could try looking at individual processes for example MPD.

Code:

sudo systemctl status mpd

Other suspects for the symptom "system crashes" include bad SDCard, flakey power supply, other hardware issues. The easiest way to troubleshoot these types of issues is to swap in known good media and hardware.
