[Debian-iot-maintainers] Bug#1071721: [mosquitto] mosquittostart-stop-daemon: unable to open pidfile '/run/mosquitto/mosquitto.pid' for writing (No such file or directory)

[Jean-Marc LACROIX]

Package: mosquitto
Version: 2.0.11-1.2+deb12u1
Severity: grave

Is seems that on  package mosquitto (Debian 12.5  Bookworm), is is not
possible to install the package & start the daemon.

Please  note following  example are  done  on amd64  architecture, but
behaviour is the same on others architectures.

This bug is probably due to the directory created with the pid file.

ansible at hn-asusgl752-400:~$ LC_ALL=C dpkg -l |grep mosquitto
ii  libmosquitto1:amd64                      2.0.11-1.2+deb12u1

It seems that following line can correct launching o daemon

    sed -i -e 
's#PIDFILE=/run/mosquitto/mosquitto.pid#PIDFILE=/run/mosquitto.pid#g' 
/etc/init.d/mosquitto
