gpg Timeout in WSL1 when signing

Question

I am new to GPG keys. I created two in WSL to sign my git commits.

However, I cannot use these keys because all sign commands would time out.

gpg-agent

gpg-agent[2416]: gpg-agent running and available

echo "test" | gpg2 --clearsign

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512

test gpg: signing failed: Timeout gpg: [stdin]: clear-sign failed: Timeout

gpg2 -K

Output:

/home/ME/.gnupg/pubring.kbx
-----------------------------
sec   rsa4096 2022-01-06 [SC] [expires: 2022-01-07]
      ...

ssb   rsa4096 2022-01-06 [E] [expires: 2022-01-07]

Remove personal GPG key also times out:

gpg --delete-secret-keys [email protected]

gpg: deleting secret key failed: Timeout gpg: deleting secret subkey failed: Timeout gpg: [email protected]: delete key failed: Timeout

• I tried with gpg and gpg2
• I added export GPG_TTY=$(tty) to ~/.bashrc
• I tried with pinentry-tty

Environment:

• WSL1
• Ubuntu 18.04.6 LTS

After restarting Windows, the timeouts were gone.

I did a number of things and I cannot say if any of these thing caused the timeouts to disappear beyond mere restart:

• disable IPv6 in Windows

sudo update-alternatives --config pinentry
> Choice 3 (tty)

unset DISPLAY

gpg-connect-agent reloadagent /bye

Add to bashrc

gpg-connect-agent updatestartuptty /bye >/dev/null

sudo apt install gnupg2
sudo apt-get install -y pinentry-tty
