Just some admin stuff first up. Please don’t create multiple posts for the same thing. You already have a post open here (Tedge -mapper unmet dependencies), where I’ve responded that the i386 architecture is not supported by thin-edge.io. Having multiple posts for the same thing makes it very difficult to help you and for other people in the future to follow.
Ok, now to the technical part.
Whilst your CPU architecture (x86_64) is supported by thin-edge.io, it looks like the OS version that you are using does not. In essence you’ve used the 32 bit variant of Debian bullesys which means that all of the applications are running 32 bit versions rather than the 64 bit version.
The Debian architecture can be viewed by running the following command:
dpkg --print-architecture
The only way to fix this is to use the 64 bit version of the selected operating system, however this will mean redownloading the image, and reinstalling the whole Operating System.
You should be able to find a suitable Debian image which uses amd64 (not i386) on the official Debian website:
