Mosquito fails to start

Post by Nizzel »

Hi all
Hoping you can help. I’ve installed several bits of software but one of the main ones I want is Mosquito. I don’t have a lot of Linux experience and have spent a lot of time googling this to no avail.

Here is as much information as I can find to give you:

RPi 3 Model B (armv7l)

[ OK ] DietPi-Services | restart : proftpd
[ OK ] DietPi-Services | restart : minidlna
[ OK ] DietPi-Services | restart : squeezelite

[ OK ] DietPi-Services | restart : urbackupsrv
[FAILED] DietPi-Services | restart : mosquitto
[ OK ] DietPi-Services | restart : cron
[ OK ] DietPi-Services | restart : dropbear

Well than you would need to create the missing log folder

Code: Select all

mkdir /var/log/mosquitto
chown mosquitto /var/log/mosquitto
chmod 755 /var/log/mosquitto
than try to start mosquitto manuell again
