pacman -Ql brave-bin

Questions

Why does this site list only the cachyos repo?

One rule keeps every guide simple: only apps packaged in the official CachyOS repo. Each one installs with a plain pacman command, comes as a signed package and updates with the rest of your system.

What are the CachyOS optimized repos?

CachyOS rebuilds many packages for newer CPU levels such as x86-64-v3, x86-64-v4 and Zen 4. pacman picks them automatically on supported hardware, so the install commands stay the same.

What if pacman shows a signature error?

The CachyOS FAQ says a PGP signature error points to a problem with your system's pacman keyrings, which verify the authenticity of packages. Follow the steps in the CachyOS FAQ to refresh them, then try again.

Is there a graphical app store on CachyOS?

Octopi and Shelly are graphical package managers in the cachyos repo.
