Recently I have updated the readme file of how to build talkkonnect on https://github.com/talkkonnect/talkkonnect since there are many changes to raspbian (now called raspberrypi os) and also the links for downloading and installing golang.
The latest instructions tested as of today (07/06/2020) work as intended. Sorry to all the folks who wasted their precious time to try to get talkkonnect to compile and install following my previous instructions working as they were pretty dated.
Thank you to all the folks who continue to build and play with talkkonnect and take the effort to send me a short email letting me know about your particular use case of talkkonnect and the pictures of your build.
