[BUG] Claude Code runs the game Pacman in /usr/games/pacman on PopOS

What's Wrong?

Claude Code is running pacman -Qo to check which package owns the binary file. That's an Arch Linux command to query package ownership.

But on Pop!_OS (Ubuntu-based), where pacman isn't the package manager - it's the Pac-Man game at

/usr/games/pacman

So Claude Code thinks it's querying package info, but it's actually launching the game with garbage arguments, which the game ignores and just runs.

This is a bug in Claude Code - it assumes pacman = Arch package manager without checking the distro

What Should Happen?

Claude should use the correct package manager
