dbermond [1] filed a deletion request for virtualbox6.1-bin [2]: I'm the package maintainer. VirtualBox 6.1 only supports linux kernel up to 6.6. It does not support the current linux-lts 6.12 and linux 6.13 in the official repositories. Since linux-lts have switched from 6.6 to 6.12, and there is no linux6.6 in the AUR, the package becomes permanently unsupported and broken.
