Debian and Raspbian Packages

Hosted By: Cloudsmith

We now build Debian packages for amd64, armhf and arm64 and Raspbian packages for armhf as part of our releases. Unfortunately Debian armhf packages do not run on Raspberry Pi 1 although the architecture on the RPi is named armhf. Using Raspian armhf packages fixes that.

The ones attached to the release are meant for debian trixie. These and packages for bookworm and bullseye are also provided through a repository graciously provided by Cloudsmith.

The setup of the repository is also explained by Cloudsmith. This boils down to adding a file to /etc/apt/sources.list.d/ containing

deb [signed-by=/usr/share/keyrings/volkszaehler-volkszaehler-org-project-archive-keyring.gpg] https://dl.cloudsmith.io/public/volkszaehler/volkszaehler-org-project/deb/debian bookworm main
deb-src [signed-by=/usr/share/keyrings/volkszaehler-volkszaehler-org-project-archive-keyring.gpg] https://dl.cloudsmith.io/public/volkszaehler/volkszaehler-org-project/deb/debian bookworm main

You need to replace bookworm with your distro and debian with raspbian in case you are using an RPi 1. You also need to retrieve our repository key as a trusted one.

curl -1sLf "https://dl.cloudsmith.io/public/volkszaehler/volkszaehler-org-project/gpg.21DBDAC56DF44DA1.key" | \
	gpg --dearmor > /usr/share/keyrings/volkszaehler-volkszaehler-org-project-archive-keyring.gpg

There is also a libsml package that is part of Debian. While the version in older Debian releases is somewhat outdated the version in trixie is recent. Other than the project packages the official Debian package has a version postfix separated by a hyphen (e.g. 1.0.2-3). It has minor differences in packaging and is maintained as part of the project in the debian branch.
