(Originally reported by Brad Marshall at https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1421075. This is an obvious one-line fix in clientloop.c.) When using ssh and managing ssh port forwards with ~C to remove a forward that doesn't exist, the following occurs: user@host:~$ ssh> -KD12345 Unkown port forwarding. i.e., the misspelling of the word Unknown as 'Unkown'.
Fixed, thanks.
Close all resolved bugs after release of OpenSSH 7.7.
