amazon-ebs: Error waiting for SSH: handshake failed: ssh: unable to authenticate

[c2cschools]

I noticed that this problem has occurred before in #130 , but I am not sure if this is the same issue.

I am attempting to build my images in stages. I go from the official release ami to a "raw" image, then from the "raw" image to a "bootstrapped" image.

official -> raw -> bootstrapped -> base

Where "raw" is basically a local copy of the official image, bootstrapped includes Puppet and Docker, and the base image is the result of a Puppet Apply run that installs and configures our commons.

I am creating AMIs/images for Ubuntu 12.04 and CentOS 6.4.

With Ubuntu, I have successfully completed the "raw" and "bootstrapped" images. With CentOS, the "raw" image builds fine (though I had to increase the ssh_timeout setting). However, when going from "raw" to "bootstrapped" with CentOS, it fails with:

==> amazon-ebs: Error waiting for SSH: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

It's worth noting that my "raw" build executes a shell script, but that shell script is empty, so no filesystem changes have occurred, that I am aware of, that could have caused this problem.

[intabulas]

I am also seeing this today

[tomasca]

Also seeing the same thing. Tried with packer 0.5.1 today. Had same thing with 0.4.1 before.

Even when launching the Packer-created "raw" image manually via EC2 console it is not possible to manually login with SSH and keypair. It asks for password.

Only issue with CentOS. Works as expected with Ubuntu and RHEL.

[kevinmartin]

I get the same error. Using CentOS.

[shahab32mohsen]

Same here, I get the same error using CentOs. I can successfully create the Virtual network, Cloud service, VM, Disk, .... but at the end before running provisioners it fails with exactly same error! Has anybody found a solution yet?:)

[inbravo]

The same issue is with me. Tried with,

1. Medium instance of Ubuntu (ubuntu-precise-12.04-amd64-server-20120616-5cc062dc-4b61-4424-bc43-416e51483a1f-ami-82fa58eb.1 (ami-967edcff))
2. Received this error: Error waiting for SSH: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

[ddeboer]

Same error message here with a CentOS 6.5 image.

[dsummersl]

Same here, Amazon Linux AMI ami-bba18dd2

[mwedgwood-rmn]

The problem is (arguably) the timing of when the vanilla CentOS image gets its ssh keypair from the metadata server. The bit of code that does it is in rc.local, and that runs after SSH starts up. Depending on when packer tries to authenticate, it might catch a listening SSH daemon but no authorized key for the root user.

It would be awesome for packer to optionally retry failed SSH authentication.

[felin-arch]

I just ran into this problem and spent an hour trying to figure out what the hack is happening. Here is my scenario which is pretty similar to yours. I wanted to set up a minimal environment in amazon based on CentOS 6. All I wanted is a fully patched AMI so I could start provisioning on top of that. I ran into the same handshake failure problem.

Here is what is happening:
The original CentOS ami has a script (/etc/rc.d/rc.local) which fetches the public-key from amazon and sets it up for the root account. This script only tries to fetch the keys if the root account does not have any associated keys with it (/root/.ssh/authorized_keys does not exist). This is the case with the base image, but once you "repackage" it, it will hold the initial public keys (fetched from amazon during this "provisioning" session), hence when you boot up your own AMI the script will not fetch the keys from amazon (because root already has keys).

I simply did an "rm -rf /root/.ssh/authorized_keys" after patching up the AMI. In my case this had nothing to do with packer, it was the CentOS key fetching script which held the solution.

[blandonnimrat]

@felin-arch - thank you so much for writing that up. My hair is (somewhat) intact because of your gentlemanly contribution.

[mwedgwood-rmn]

@felin-arch, this does indeed fix one case of the problem described by the OP, but the problem also exists when going from official -> raw. If @mitchellh considers this one closed, I can file a new bug detailing the issue from the official image.

My workaround was to build a new base image by installing into a chroot and configuring cloud-init to handle the key setup, removing the bits in the dist rc.local.

[i-sam]

@felin-arch @mwedgwood-rmn Guys, so is the problem was solved in somehow, still see the same problem with Centos6.5.
"==> amazon-ebs: Error waiting for SSH: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain"
Or just one way - workaround with manual rebuilding base ami?

[felin-arch]

@i-sam,
short: this is not an issue with packer. The above described two workarounds can be used to avoid this behavior.
long: I do not think packer can do anything reasonable to solve this issue. Packer works as it should, the inconsistency comes from the way the official images fetch keys. There are two workarounds above, both essentially tweak the key fetching method. As @mwedgwood-rmn, described he handles key setup in cloud-init removing the the original key setup code from rc.local. I just removed the root key right before saving the AMI so the original rc.local script would fetch it again on the next boot.

[i-sam]

@felin-arch Ok, thank you for fast answer. Got it.

[mitchellh]

I agree with @felin-arch. Sorry guys.
