how to sign the source file for the ARCH distribution - to tell the truth, it comes out that this is the only thing missing, to happiness 
Regards
oh ! Let me put it another way, what replaces the ‘makepkg’ command ?
Ok, I found the script in /usr/lib/build/bulid to build locally. The idea is that with the -dist arch’ option it should build the pkg package on the PKGBUILD substrate. And if it builds it and marks the source package by the way. However, after issuing the command it returns the error ‘expansion error preinstalls: nothing provides pacman’ even though pacman is installed. It’s already DEB package building, even though it’s tedious, but more accessible.
But I figure, simply put the handle ‘sha256sums’ in PKGBUILD. Ah… that’s how it is when one reads !
