'Aur package Showing Permission denied

Hello folks actualy i'm making an AUR package for arch linux and i have made the PKGBUILD file with reference through various YouTube videos and Blog post and Official AUR packaging documentation all i want is to move the python scripts to the /usr/bin/ directory but its throwing error of permission denied, please help

This is my PKGBUILD file for AUR package

# Maintainer: Ashwini Sahu <[email protected]>

_pkgname=hbhc
pkgname=${_pkgname}-git
pkgver=r15.e5f7975
pkgrel=1
pkgdesc="A fast and Open Source Home Baked Hash Cracker for linux Written in Python3"
arch=('any')
url="https://github.com/ASHWIN990/${_pkgname}/sssssssss"
license=('GPL3')
depends=(python3)
makedepends=(git)
source=("git://github.com/ASHWIN990/hbhc.git")
md5sums=('SKIP')

pkgver() {
        cd "$_pkgname"
        printf "r%s.%s" "$(git rev-list --count HEAD)" "$(git rev-parse --short HEAD)"
}

package() {
        cd "$_pkgname"
        install -m 644 ".man/hbhc.1.gz" "/usr/local/share/man/man1/"
        cp sha* /usr/bin/ | echo -e "MOVING THE PYTHON SCRIPTS IN /usr/bin"
        cp md5* /usr/bin/
        cp hbhc /usr/bin/
        cp .man/hbhc.1.gz /usr/local/share/man/man1/hbhc.1.gz
}

This is the error that i'm getting which making the package

Thanks to folks who give the answer and My new PKGBUILD file looks like this and also it runs without any error

(Just a heads up, I dont use Arch and I have never written a PKGBUILD for it. I am Fedora guy, but a similar error has bitten me there often enough.)

package() {
        cd "$_pkgname"
        install -m 644 ".man/hbhc.1.gz" "/usr/local/share/man/man1/"
        cp sha* /usr/bin/ | echo -e "MOVING THE PYTHON SCRIPTS IN /usr/bin"
        cp md5* /usr/bin/
        cp hbhc /usr/bin/
        cp .man/hbhc.1.gz /usr/local/share/man/man1/hbhc.1.gz
}

This code is executed when you are building the package, not when you are installing it. This is not running as a root user, but as the package-build user (I am not sure what that is, on Arch). As a non-root user, you are trying to copy your package to paths (like /usr/...) which only root can write to. That's not allowed and leads to the permission issue:

==> Starting package()...
install: cannot create regular file '/usr/local/share/man/man1/hbhc.1.gz': Permission denied
==> ERROR: A failure occurred in package().

But you dont want to run as root either. What you need to do is to install to the special location $pkgdir: https://wiki.archlinux.org/index.php/Creating_packages#Defining_PKGBUILD_variables. This special location looks like /, but you can write to it. Everything in $pkgdir becomes a part of the package you are building. Then, when you install the package you have just built, everything from $pkgdir is copied over to /.

In other words, when building a package, you install things to $pkgdir/usr/bin/foo. When that package is installed, that file gets placed at /usr/bin/foo.

package() {
        cd "$_pkgname"
        install -m 644 ".man/hbhc.1.gz" "$pkgdir/usr/local/share/man/man1/"
        cp sha* "$pkgdir/usr/bin/"
        cp md5* "$pkgdir/usr/bin/"
        cp hbhc "$pkgdir/usr/bin/"
        cp .man/hbhc.1.gz "$pkgdir/usr/local/share/man/man1/hbhc.1.gz"
}

This idea is also known as DESTDIR which is commonly documented in various make and similar tools:

Hopefully that fixes the problem for you.
