Installation of aiocoap on windows 10 failed.

Below is the result while installing DTLSSocket:

Please try installing DTLSSocket (eg. using pip install DTLSSocket) on its own. If that works, I can look into this further here; if not, please report the issue at https://github.com/kabel42/DTLSSocket.

Tried installing using pip install DTLSSocket and still observe the same behaviour.

Mh, then there's nothing aiocoap can do about this, but maybe the DTLSSocket author can. (What aiocoap could do is use a different DTLS library, see #230, but there are not really any other candidates fitting the requirements, and chances are this is just a glitch in DTLSSocket's build system).

Please report the issue at https://github.com/kabel42/DTLSSocket which is that library's public issue tracker.

On looking in a bit more closely, this may just be for lack of autoconf being installed. I haven't used Windows in ages, and don't even know how that'd be installed there.

It may still be a good idea to take this to the DTLSSocket issue tracker though -- AFAIK Python's build system can provide binary packages for platforms that don't come with build infrastructure, and maybe that should have happened and just broke somewhere.

$ sudo apt-get install autoconf
$ pip install DTLSSocket

This fixes it for me
