[New-bugs-announce] [issue37832] _Py_HashRandomization_Init: failed to get random numbers

[Jeffrey Walton]

New submission from Jeffrey Walton <noloader at gmail.com>:

I need to setup a Debian HURD test machine to investigate a problem I was seeing in the Crypto++ library. After setting up the machine and running an apt-get install for some build tools I noticed Python was failing:

    Fatal Python error: _Py_HashRandomization_Init: failed to get random numbers to initialize Python

It seems HURD no longer provides /dev/urandom out of the box. This is new behavior, and it was not present in the past. It is present in the ISO's from June 2019 (https://cdimage.debian.org/cdimage/ports/current-hurd-i386/iso-dvd/).

Python may want to employ a fallback strategy since whatever is using Python ignores the error and trucks on.

Sorry to dump this on you.
