sysupgrade on aarch64

["joelp%fastmail.com@localhost" <joelp%fastmail.com@localhost>]

Hello — I was thinking about updating to a Daily build of NetBSD 11. My current system:

rockpro64:/home/joelp$ uname -a
NetBSD rockpro64 11.0_STABLE NetBSD 11.0_STABLE (GENERIC64) #0: Sun Aug  2 14:10:41 UTC 2026  mkrepro%mkrepro.NetBSD.org@localhost:/usr/src/sys/arch/evbarm/compile/GENERIC64 evbarm

I then realized my build machine is not in great shape right now, so then thought about sysupgrade and I installed it. I tried something simple:

rockpro64:/home/joelp$ doas sysupgrade auto

sysupgrade: I: Starting auto-update with stages: fetch modules kernel sets etcupdate postinstall clean

sysupgrade: I: Downloading https://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-11/latest/evbarm/binary/sets/base.tgz into /var/cache/sysupgrade

ftp: Error retrieving file `404 Not Found'

sysupgrade: E: Failed to fetch https://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-11/latest/evbarm/binary/sets/base.tgz

Then I looked in /usr/pkg/sbin/sysupgrade and noticed this:

    if [ "$(uname -p)" = 'x86_64' ] || [ "$(uname -p)" = 'sparc64' ]; then

        shtk_config_set ARCHIVE_EXTENSION "tar.xz"

    else

        shtk_config_set ARCHIVE_EXTENSION "tgz"

    Fi

Currently, the endpoint where it tries to fetch is "tar.xz", not "tgz", hence the 404.

Questions (assuming my build machine is still broken):

1. What should ARCHIVE_EXTENSION be really? Bug in sysupgrade?
2. Is Daily a good place to get any binary security patches?

Thanks - Joel
