Fix CI checks

[jnross]

I investigated the CI failures and discovered it was a non-zero exit code from a call to apt-get update that was causing the workflow to fail. In order to fix this, I had to fork the gha-ubuntu-cross repo and apply the fix there. I'm working to get this fix upstreamed in cyberjunk/gha-ubuntu-cross#6. Once it is, we can revert this reference back to the original repo.

I also fixed a clippy warning that was added 1.72.0. https://rust-lang.github.io/rust-clippy/master/index.html#/single_range_in_vec_init The page says "this is almost always incorrect", but it seems clear that this is quite intentional in our case here. So I silenced the warning by adding an #[allow annotation.

I updated this PR with an improved fix for gha-ubuntu-cross and included the fixes from #467 so checks will pass.
