From dac933e4e0226e779382543660732ef3e02910bd Mon Sep 17 00:00:00 2001 From: Ross Burton Date: Wed, 24 May 2023 18:14:34 +0100 Subject: python3-pydbus: remove obsolete recipe This project has been untouched since 2018 and doesn't appear to have any real dependents. If something similar to pydbus is needed, then a maintained alternative would be https://github.com/rhinstaller/dasbus (recipe available in meta-anaconda).
