Just thought I'd reinstall #OpenBSD 7.9 again and then switch to the latest snapshot to see if my not being able too boot /bsd past the 14th May snapshot and it now fails to verify the downloaded stuff 😂
Good thing I've still my trusty #FreeBSD laptop.

Even more random redoing the sysupgrade -s and it passes straight away and upgrades. Does it boot the /bsd ? No it does not only boot.rd and boot.sp boot.

@justine Don't worry. That happens from time to time if you use the CDN. It fails because the signature file was already synced from a newer snapshot and the remaining files are still in transit.

Either wait some time or use a non-CDN mirror.
