I would guess that "Build Files Exist" means makepkg successfully downloaded the files it needs to build the package. I assume cleanBuild is referring to the building of packages itself.
As for the options, my guesses are:
N
don't install anything and continueA
build and install all the listed packagesAb
interrupt everything and exitI
rebuild packages which are already installed, but don't install new onesNo
build and install packages which are not installed on the system
I think you can also pick specific packages by referring to their index
- either listing them all (
1 2 3
) - specifying a range (
1-3
) - or excluding those which you don't want (
^4
)
Note that I don't use arch btw so I'm only guessing.
Tbh I doubt users would notice. If you have a USB cable near you, check if the USB A plug has a blue core, or you can count how many connections there are inside. If its not blue and has four connection (or five in the case of mini / micro versions), its USB 1.x/2.x. USB 3.0+ should be blue and has nine connections (except for USB C, which has 24). USB 1.x/2.x cables seem to be everywhere, at least where I live. And yes I'm saying 1.x/2.x because both use the same connectors and cables, with additions in 1.1 and 2.0 revised.
