I'm trying to get wine-devel to upgrade on Ubuntu 21.04, and there seem to be no more version conflicts or hash issues, but it seems it can't find the libvkd3d-headers package (it "has no installation candidate"). Is something wrong on my side?
It is not you, it is the repo. If you need the packages, you can download them manually from https://dl.winehq.org/wine-builds/ubuntu/dists/hirsute/main/binary-all/
If you install the headers package by itself, libvkd3d-dev should stop complaining.
Someone is probably working on figuring out why some files/directories does not sync correctly.
