Unable to install a specific font cask

[Kreeblah]

I noticed that the font-fira-mono-nerd-font cask got updated when I updated my casks, but the update failed. Uninstalling/reinstalling the cask fails, too, with the following sequence of events (for brew install --cask --verbose font-fira-mono-nerd-font):

==> Purging files for version 2.2.1 of Cask font-fira-mono-nerd-font
Error: It seems the Font source '/opt/homebrew/Caskroom/font-fira-mono-nerd-font/2.2.1/Fira Mono Bold Nerd Font Complete.otf' is not there.

What's really weird about this is that there seems to be a purge running (deleting the font files from the downloaded ZIP file) before it begins moving the font files to my user's Fonts directory, and I can't figure out why that's happening.

I can install other font casks just fine, but this one seems to consistently fail on my system. brew doctor just reports some unbrewed dylibs, static libraries, and headers, the permissions on /opt/homebrew/Caskroom are correct (owner: my user, group: admin, 0775), and it seems to be isolated to this one font cask, but the cask code looks pretty much the same as any other. I even tried deleting the downloaded zip file out of the Homebrew cache in case that somehow mattered, but there wasn't any change.

Has anybody else ever seen something like this?

The issue is that the font files within the .zip are all titled Fura instead of Fira, which is what the cask expects. There is an issue for this upstream: ryanoasis/nerd-fonts#1003

Ah, good catch. I missed the spelling change there.

Thanks!
