You would be surprised as how many people end up showing they were installing something else entirely, especially with software with many related packages like chrome is.
google-chrome-stable doesn’t exist. I’m assuming you mean
So, the pkgbuild file for that package doesn’t suggest any git dependency, directly or indirectly. And I just know for a fact that the
google-chrome-stable.sh file that is also downloaded doesn’t have a git requirement. This clearly indicates some requirement being generated by
pamac itself. But I don’t use
pamac, so someone else needs to confirm this.
