Using Fedora 38, say you want to update the package albert from manuelschneid3r, hosted at https://software.opensuse.org/download.html?project=home:manuelschneid3r&package=albert.
And with dnf update, you get the following output:
~ sudo dnf update
Dependencies resolved.
Scalable Vector Extensions (SVE) is ARM’s latest SIMD extension to their instruction set, which was announced back in 2016. A follow-up SVE2 extension was announced in 2019, designed to incorporate all functionality from ARM’s current primary SIMD extension, NEON (aka ASIMD).
Despite being announced 5 years ago, there is currently no generally available CPU which supports any form of SVE (which excludes the [Fugaku supercomputer](https://www.fujitsu.com/global/about/innovation/

| # For most Homebrew tools, their presence in /usr/local/bin and that being in your $PATH | |
| # means you can use them as-is, but some tools appear with different names because macOS | |
