"wine is not available for the x86_64 architecture" even though I have wine installed?

I am trying to install world of tanks blitz, but right after I click install, a message pops up saying “wine is not available for the x86_64 architecture” even though I’ve installed wine 3.10 x86_64 and wine staging-3.10 x86_64. what is the problem?

Are you still encountering this error?

We should have got rid of that a few releases ago so I’m thinking it was maybe a temporary network error?

I get the same error when installing Medieval Engineers. Why are we getting this error message and what can be done to fix it?
