Ubtuntu 18.04 Package - Timeout Starting Service (but it starts..)

[peterchs]

Following on from fix for #1425 I attempted to update packages. 1.6.7 was picked up, however this failed on upgrade.

I then purged/removed mosquitto and mosquitto clients packages which also uninstalled the lib package (to try and rule out config or environment problem);

apt-get purge --auto-remove mosquitto
apt-get purge --auto-remove mosquitto-clients

and attempted to reinstall. I am getting the following;

# apt-get install mosquitto mosquitto-clients

The service starts a process ok, its just not playing nicely with systemd in type notify mode.

I changed /lib/systemd/system/mosquitto.service to have Type=simple instead of notify, and the service is starting without error now. Also it automatically restarts when I kill -9 mosquitto PID.

Sorry about that, a missing build dependency meant it wasn't building with systemd support, but wasn't failing at build time either. If you update now it should be fixed.

Confirmed new build 1.6.7-0mosquitto2~xenial1 (for Ubuntu 16.04) corrects the notify issue. Thanks.

[peterchs]

Likewise updated 1.6.7 installed and service started without issue. Confirmed notify systemd working. Kill -9 mosquitto pid and it restarted. Perfect. Thanks ralight. Closing issue.
