I installed eclipse mosquitto in a container on an Rpi4B and it is working, can publish and subscribe. However, whenever I run sudo apt upgrade, I get this error report:

I am using mosquitto version 1.5.7 and built the container this way:

sudo docker run -itd
–name=mqtt
–restart=always
–net=host
-v /mosquitto/config:/mosquitto/config
-v /mosquitto/data:/mosquitto/data
-v /mosquitto/log:/mosquitto/log
eclipse-mosquitto

Is there a way to get rid of the apt upgrade error messages? Thanks for any help.

Where do you run this? In the container?

Thats not how containers work :slight_smile:

Instead you should check if there is a new version of the image, you can try to do an

docker pull eclipse-mosquitto

and see if it pull down anything, if it does, then you need to re-create your container

Thanks for the prompt reply. I run sudo apt update and sudo apt upgrade in a regular terminal window and get that error. The docker pull eclipse-mosquitto command tells me the my image is up to date for eclipse-mosquttto:latest.

When mosquitto is running in the container, you dont need it on the host.
I would simply delete it from the host if you dont plan on using it, but plan to use it in the container instead

I installed some other programs, including numpy, and it seems one of them could not see mosquitto running in the container and installed it in the host, getting errors. I decided to remove the container, and let it run on the host instead. It is working on my docker program homeassistant, so I will leave it like that. Thanks again; I am new to docker.
