New comment by UK82 on void-packages repository https://github.com/void-linux/void-packages/issues/22366#issuecomment-635151127 Comment: Thank you for your mutual responses.. In regard to ericonr's comments, I did check to determine whether cinnamon-settings-daemon was installed and can confirm it is/was.. Re not-chicken's recommendation I confirmed python3-distro wasn't in fact installed and after installing this and rebooting I was then able to once more gain access to the Control Centre. The residual warning notification re a broken extension etc. prevailed but as suspected that was a result of the sole extension I have installed presumably not having caught up with the upstream Cinnamon stuff and once disabled, disappeared on the next reboot. As a result all sorted, thank you both! :-)
