MarsSeed [1] filed a deletion request for teamviewer8 [2]: Orphaned package for TeamViewer 8 from 2012. There was a point release in 2020 but no one updated it here. It has been declared End-of-Life on September 15, 2021. It can no longer connect to other clients via the internet. Current release is TeamViewer v15. I suggest to delete this now deprecated version.
