[SOLVED] Openhabian-config upgrade issue (mosquitto)

All,

i have an issue (not critical maybe) since quite a few months.
I am running openhabian 1.4.1-413 and do an update upgrade every now and then.

updating works fine - at the end of the upgrade though I get an error related to mosquitto:

WARNUNG: Die folgenden Pakete können nicht authentifiziert werden!
  mosquitto-clients libmosquitto1 mosquitto
E: Es gab Probleme und -y wurde ohne --force-yes verwendet.
FAILED

Which actually means:

WARNING: the following packages could not be authenticated.
mosquitto...
There were problems and -y was used without --force-yes.

So it seems mosquitto has not been upgraded on my system since a few months.
Any suggestions?

You can try:

sudo apt-get install --only-upgrade mosquitto

Thanks, that di the job

Unfortunately I cannot connect anymore since.

But my config is:

log_type notice
log_type information

I actually don’t know where all these

come from…
