Should `Failed to download {pkg}` fail immediately?

As part of this run, you can see this message

✖ Failed to download rcmdcheck 1.4.0 (source)

But it doesn't stop there, the installation process continues and we finally get an obscure error here:

We wondered if possibly this should have exited earlier when the package couldn't be downloaded
