<![CDATA[Python3 support?]]>Python2 is EOL as of 1/1/2020. The python-minimal package is no longer available in newer versions of Ubuntu. Is there a plan to support building from source using Python 3 instead?

There seems to be an incompatibility with node-gyp and python3. This is what I'm getting when running the initial yarn command --

Why not just bump the minimum argon2 package requirements for hashy?

Is there a way to force the process to use argon2@0.26.1 instead of argon2@0.25.1?

FYI, the issue appears to be related to xo-server > hashy > argon2.

However, we'll keep an eye on next Debian if it requires some changes.

Regarding the dep "problem" with Python, I have no idea myself.
