  but downgrading openssl package is not desirable for security reasons.

  per https://github.com/pyca/cryptography/issues/7959 and other hits on search, cryptography package 39.0.0 is incompatible with pyOpenSSL 21.0.0; cryptography 38.0.4 works with 21.0.0; cryptography 39.0.0 requires 22.1.0 or greater.
  Installed packages are python3-cryptography 3.4.8-1ubuntu2 and 21.0.0-1 python3-openssl
  Currently, python3-openssl 22.1.0 is not available from repo.

  $ lsb_release -rd:
