Unable to import GPG key

Summary

Can't add GPG keys generated with GnuPG for Linux running on WSL2 for Windows.

Steps to reproduce

  1. Generate a GPG key in Ubuntu or Debian on WSL2 for Windows
  2. Try to add it under GPG keys in user profile settings

Example Project

N/A

What is the current bug behavior?

Adding a GPG public key results in the following error message:

The form contains the following errors

  • Fingerprint can't be blank
  • Primary keyid can't be blank

What is the expected correct behavior?

The dialog accepts the pasted public key and adds it to my profile. I've tested several keys and all have the same issue. I tested the keys on GitHub and they were added without issue.

A key I generated using GnuPG for Windows on the same machine was accepted.

Relevant logs and/or screenshots

Example key which reproduces this behaviour. It's 1024-bit RSA simply for brevity; the behaviour replicates with 4096-bit RSA as well:
