I used this command to import the key

gpg --keyserver pool.sks-keyservers.net --receive-keys 0D96DF4D4110E5C43FBFB17F2D347EA6AA65421D

I have imported and signed the GPG key: pacman-key --list-keys

pub   rsa4096 2014-11-02 [SC]
      0D96DF4D4110E5C43FBFB17F2D347EA6AA65421D

But I'm still getting a GPG error and I'm not sure why:

==> Vérification des signatures des fichiers sources grâce à gpg…
    Python-3.7.9.tar.xz ... ÉCHEC (Clé publique inconnue 2D347EA6AA65421D)
==> ERREUR : Une ou plusieurs signatures PGP n’ont pas pu être vérifiées.

@DMolt, it make sense to follow what is done for python35 and python36 in that regard and go without ensurepip.

Hi, I use python 3.7 for some projects with virtualenv and 3.8 for other and system. To install this I have to change --with-ensurepip with --without-ensurepip

@surrealistic above in the logs, you should see why the _posixsubprocess module is not building successfully.

Hi! I'm having this issue with subprocess while tying to upgrade python37 and also after uninstalling it to try a clean installation of it.

It's like it can't find or recognize subprocess. I searched on Google about the error and I've tried to install subprocess32 with python3.7 -m pip install subprocess32 but it returns the same error. After all those attempts I decided to try a clean installation so I removed python3.7 to install it again instead of upgrading it, but it keeps returning the same error.

Thanks greut, and thanks 5long for initial package.

You can click "Adopt Package" in "Package Actions" in the top right. Then it's yours. :D

If 5long don't/won't update the package, I could take over if that's possible (I don't know how to transfer AUR package owership…)
