That's because it uses the distro python3-cryptography, which provides
the problematic function.

You're welcome :)

Title:
  carbon-cache not starting because python3-openssl throws error
  _lib.OpenSSL_add_all_algorithms()

Status in openssl package in Ubuntu:
  Invalid

Bug description:
  1) ubuntu release:
  We are using Ubuntu 22.04 LTS:
  Description:    Ubuntu 22.04.2 LTS
  Release:        22.04

  2) packages:
  We have the following packages installed:
  graphite-carbon/jammy,jammy,now 1.1.7-1 all
  python3-openssl/jammy,jammy,now 21.0.0-1 all
  OpenSSL: OpenSSL 3.0.2 15 Mar 2022 (Library: OpenSSL 3.0.2 15 Mar 2022)

  3) Expected result
  The carbon cache should start if all dependent packages are from the same repository.

  4) observed issue
  Since the last OpenSSL update this week via the ubuntu repository, the carbon-cache service is not starting any more.
  The error message is:

  According to https://levelup.gitconnected.com/fix-attributeerror-module-lib-has-no-attribute-openssl-521a35d83769 the python module pyopenssl needs to be > 22.1.0
  Ubuntu 22.04 LTS ships with version 22.0.0.
  It seems, that the python3-openssl is not working well with the most recent openSSL version of Ubuntu 22.04.

  I could update pyopenssl with pip but this might break the update
  mechanism of apt.

  Any suggestions are appreciated, thanks!
  If I can provide further information, just let me know.
