I think this issue may have to be resolved by the maintainers of the
package that broke my machine at that time. Going through logs, it
appears that an HPLIP (HP Linux Imaging and Printing) update was the
actual culprit in this case, by installing their required version of
these packages as system-wide versions.

Thank you for the response, and my apologies for not addressing this bug
sooner. It should be Resolved as Invalid. (I'll see if I can do that
myself.)

  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.
