Output of brew doctor

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: No developer tools installed.
Install Clang or run `brew install gcc`.

Warning: Your /home directory is a symlink.
This is known to cause issues with formula linking, particularly when installing
multiple formulae that create symlinks in shared directories.

While this may be a standard directory structure in some distributions
(e.g. Fedora Silverblue) there are known issues as-is.

If you encounter linking issues, you may need to manually create conflicting
directories or use `brew link --overwrite` as a workaround.

We'd welcome a PR to fix this functionality.
See https://github.com/Homebrew/brew/issues/18036 for more context.

Description of issue

While I'm able to install casks like fonts, e.g., font-iosevka, I cannot search for them.

For example,

$ brew info font-iosevka
==> font-iosevka ✔ (Iosevka): 34.3.0
https://github.com/be5invis/Iosevka/
Installed (on request)
/home/linuxbrew/.linuxbrew/Caskroom/font-iosevka/34.3.0 (420MB)
  Installed using the formulae.brew.sh API on 2026-04-16 at 19:46:16
From: https://github.com/Homebrew/homebrew-cask/blob/HEAD/Casks/font/font-i/font-iosevka.rb
==> Requirements
Required: macOS >= 10.15 (or Linux) ✔
==> Artifacts
Iosevka.ttc (Font)
==> Analytics
install: 604 (30 days), 1,878 (90 days), 7,192 (365 days)

Trying to search for them always gives me negative results:

$ brew search font-iosevka
Error: No formulae or casks found for "font-iosevka".

Is it a limitation due to the immutable nature of Fedora Silverblue?
Please, keep in mind that I'm totally new of Fedora Silverblue, I just started experimenting with that.
Usually, I don't use Homebrew in Linux, but I seem to recall that when I tried that in other distributions, search for casks used to work.

Thanks in advance

It's the same on Ubuntu.

Should be fixed by Homebrew/brew#22677.

Works fine now. Thanks!
