@strowk unfortunately we don't support Ubuntu 20.04 for APT at this time. From the link you've pasted:

https://github.com/Azure/azure-iot-sdk-c/blob/master/iothub_client/readme.md#apt-get-packages-for-linux-devices

At this point you can use the packages on Ubuntu 16.04 and 18.04 using the following CPU architectures: amd64, arm64, armhf and i386.

The only workaround at the moment is to build from sources (https://github.com/Azure/azure-iot-sdk-c#compile-the-sdk).

We are going to consider support for APT packages internally. Please upvote this issue if you require Ubuntu 20.04 APT package support.
