I don’t usually use VS code but if it can help - I did a fresh installed Code OSS - with the purpose of answering the question.

 $ pamac info code | grep -e 'Version' -e 'Packager' -e 'Build Date'
Version               : 1.100.2-1
Packager              : Massimiliano Torromeo <mtorromeo@archlinux.org>
Build Date            : tor 15 maj 2025 20:05:34 CEST

Installing Python extension throws a message on the inability to verify extension signature

The message is Signature verification failed with ‘UnknownError’ error.

The options are

  • Install Anyway (Don’t Verify Signature)
  • Report Issue
  • Cancel
  • Learn More

Where the first option will let the extension setup continue successfully.
