Virtualbox 6.1.30 missing dependency libvpx6

[BertN45]

Installation of the latest Virtualbox impossible due to missing dependency, see added screenshot. That package can't be loaded with apt. "sudo apt install libvpx6" says:

Package libvpx6 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source.

Note that I could install an earlier version of Virtualbox 6.1.29 on an earlier version of Jammy Jellyfish without any issue.

I am getting this exact error on installation of jami. jami-daemon needs libvpx6, and when I try to install that latter package, it is reported as missing.
