After installing MSYS2 installer 32bit for Windows 10, I followed the instructions given on http://scipy.github.io/devdocs/building/windows.html#building-openblas to build OpenBLAS. After an apparent successful installation, I open a MSYS2 MinGW terminal and type the following: pacman -S --needed base-devel mingw-w64-i686-toolchain mingw-w64-i686-cmake git. I got the error message:

MSYS ~ $ pacman -S --needed base-devel mingw-w64-i686-toolchain mingw-w64-i686-cmake git error: mingw32: key "5F944B027F7FE2091985AA2EFA11531AA0AA7F57" is unknown :: Import PGP key 5F944B027F7FE2091985AA2EFA11531AA0AA7F57? [Y/n] y error: key "5F944B027F7FE2091985AA2EFA11531AA0AA7F57" could not be looked up remotely error: mingw64: key "5F944B027F7FE2091985AA2EFA11531AA0AA7F57" is unknown :: Import PGP key 5F944B027F7FE2091985AA2EFA11531AA0AA7F57? [Y/n] ????????????????????????????????????????????????

This error occurs throughout using other command: pacman -Syu.

The version of MSYS2 installed is:

Mintty 3.1.4 (i686 -pc-msys) Created by Andy Koppe/Thomas Wolff

Any suggestions are welcome and appreciated for assistance to resolve the issue.

  • I have been to this page about creating your own GPG key: https://fedoraproject.org/wiki/Creating_GPG_Keys#Creating_GPG_Keys_Using_the_Command_Line. I entered the command "gpg2 --full-gen-key", in MSYS2 terminal. The command is not recognized. – Chi Ho Nov 14 '21 at 13:52
  • Thank you for your email reply. Yes. I'm using Windows 10 32 bit. I suppose I can upgrade the Windows 10 32 bit to 64 bit by a new installation. But, I need to install OpenBLAS in order to install scipy. I need to use MSYS to install OpenBLAS. Any helpful suggestion is welcome and appreciated. – Chi Ho Nov 14 '21 at 14:22
