This is the second time i've told off this budding developer, and i'm worried i'm harming them. If they were more welcome they could participate in open efforts more. I also don't know why somebody would build a website, and i'm worried it could be for mitm attacks, from my paranoia.

Is this question on-topic for this list, or would it better go in a python or jinja help community?

File "/usr/lib/python2.7/dist-packages/babel/messages/frontend.py", line 911, in main It looks like your config resulted in the makefile using python2. The README says that python3 is required. I don't know if that's the cause of your issue, but it's a present issue. You can test your jinja setup with: pip3 install jinja2 python3 >> import jinja2.ext Myself, when I try to build the website, I have a different issue: ~/src/www $ ./bootstrap Synchronizing submodule url for 'build-system/taler-build-scripts' Synchronizing submodule url for 'inc' ~/src/www $ ./configure info: running with python sys.version_info(major=3, minor=9, micro=6, releaselevel='final', serial=0) required option '--variant' missing ~/src/www $ Curious if others have the --variant problem, but I understand that this isn't a support list.
