i installed which and now it works

The which utility was deprecated years ago, but is still around on Arch I guess.

@mseDgE2990: You could file an issue with the mugshot upstream project to utilize POSIX-compliant command -v as a replacement

Please read the errors and try to discern what it's trying to tell you before making a post. This is a DIY distro,  you should be able to know how to do research and how to troubleshoot these issues with some logical thinking.
