[Solved] OpenSSH 6.8p1-1 and keychain: can't determine fingerprint

Question

Is anyone else seeing this warning when starting ssh-agent via keychain?
Warning: can't determine fingerprint from the following line, falling back to filename
The keychain source seems to suggest that this shouldn't really be happening.
Is this a case of keychain, or ssh-agent, just needing to be updated for the current OpenSSH?

Answer 1

This is weird, because if I isolate that function and run my keys through it, they all pass without any error.
If you set your variable with `keys=$(ssh-add -l)` and then pipe that to this script: `echo "$keys | keytest`, it works:
#!/usr/bin/sh
shopt -s extglob
while read key; do
case "$key" in
*\ @(SHA256|MD5):[0-9a-zA-Z\+\/=]*)
echo "$key" | cut -f2 -d' '
# Fall back to filename. Note that commercial ssh is handled
# explicitly in ssh_l and ssh_f, so hopefully this rule will
# never fire.
echo "Can\'t determine fingerprint from the following line, falling back to filename"
echo "$key"
basename "$key" | sed 's/[ (].*//'
esac
done | xargs
But that is what is generating the error message...
