I have just installed ARCH on my Raspberry Pi3, and tried to install sudo.
The package obviously exists in repositories, but cannot be found.
$this->bbcode_second_pass_code('', ':: Retrieving packages...
error: failed retrieving file 'sudo-1.8.19.p1-1-armv7h.pkg.tar.xz' from mirror.archlinuxarm.org : The requested URL returned error: 404
')
I have tried several times over a 24 hour period.
