$ euca-add-keypair mykey2 > mykey2.priv $ euca-add-keypair mykey2 > mykey2.priv $ euca-run-instances -t c1.medium -k mykey2 emi-DF481077 $ ssh -i mykey2.priv 172.24.129.128 Permission denied (publickey). -- SSH key stopped working https://bugs.launchpad.net/bugs/514198 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
