SSH key pass phrase authorization doesn't work

[freebased]

Trying to authorize adding ssh key doesn't give any output.
travis.rb/lib/travis/cli/sshkey.rb
sshkey --upload ~/.ssh/id_rsa -r foo/bar The private key is protected by a pass phrase. Enter pass phrase: ********* Enter pass phrase: *********** Enter pass phrase: ************ Enter pass phrase: ********** Enter pass phrase: ***********
