Quickstart not working, setup.py install fails

Context

I want to add an app, thus I follow fdroiddata/CONTRIBUTING.md. I read

Follow the Quickstart

There, I read

Install fdroidserver, or just use it directly from master:

That, I did, cloning the repository.

Problem

These are the errors I see:

$ fdroid init
Traceback (most recent call last):
  File "/home/user/fdroidserver/fdroid", line 24, in <module>
    import fdroidserver.common
  File "/home/user/fdroidserver/fdroidserver/common.py", line 50, in <module>
    from pyasn1.codec.der import decoder, encoder
ModuleNotFoundError: No module named 'pyasn1'

$ fdroid init
Traceback (most recent call last):
  File "/home/user/fdroidserver/fdroid", line 24, in <module>
    import fdroidserver.common
  File "/home/user/fdroidserver/fdroidserver/common.py", line 50, in <module>
    from pyasn1.codec.der import decoder, encoder
ModuleNotFoundError: No module named 'pyasn1'

Tried Solutions

I thought, let's install it.
