Re: Entropy error blocks lang/python38 installation

[Andrius V <vezhlys%gmail.com@localhost>]

Hi,

This problem was reported/discussed several time I believe and I guess
it does not have final solution yet (you can check this thread:
http://mail-index.netbsd.org/tech-security/2021/01/11/msg001100.html).
However, there are workarounds to build python38 now.

One described here
https://mail-index.netbsd.org/current-users/2020/05/01/msg038495.html,
you can fool system into believing that it has enough entropy:
  dd if=/dev/urandom of=/dev/random bs=32 count=1
  sysctl -w kern.entropy.consolidate=1

Another workaround which also makes python to compile was described in
pkg/55847: https://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=55847

Regards,
Andrius V
