Sorry for the multiple posts. I edited the APKBUILD to set pkgver to the full date tag "YYYYMMDDHHMM" and used ci=$pkgver in the source url. I'm setting the download source filename to $pkgname-$pkgver.zip I ran abuild checksum twice with two different date tags in pkgver and abuild computed the same checksum <pre> sha512sums="-snip-06a13d althttpd-202005092232.zip </pre> <pre> sha512sums="-snip-06a13d althttpd-202004281307.zip </pre> I'm probably doing something obviously wrong here but I'm not seeing it.
