Comment 2 for bug 1983999

I have the inverse problem:
Using Ubuntu 22.04.1 jammy and can't install libheif1 because it requires libdav1d6.
I downloaded the package from the website: "libheif-dev (1.12.0-2build1) [universe]" and installing the .deb manually works.
Even though
apt list --upgradable
shows: libheif1/jammy 1.13.0-1~22.04.sav0 amd64 [upgradable from: 1.12.0-2build1]

So as far as I understand "apt install libheif1" wanted to install version 1.13 but that depends onlibdav1d6 which is not in the jammy repo.
