[Systems] Failing backups on freedom

[Chihurumnaya Ibiam]

Just looked at the faillog and it seems freedom couldn't access sunjammer;

root at sunjammer.sugarlabs.org: Permission denied (publickey).^M
rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: unexplained error (code 255) at io.c(235) [Receiver=3.1.2]
Wed Dec 25 06:27:47 EST 2024: rsync test failed: 255.  Aborting.

The logs on papert also confirms this;

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@^M

I've confirmed the keys are where they should be, removing sunjammer from
known_hosts should potentially fix this
but I'm wondering why its identity changed in the first place.
