I'm trying to create a packer image of Ubuntu 20.04 using the cloud image (ubuntu-20.04-server-cloudimg-amd64.img), but it fails with error "handshake failed: ssh: unable to authenticate, attempted methods [none], no supported methods remain" when attempting to SSH to the packer vm and eventually times out.

Paste a full trace by launching packer with PACKER_LOG=1 packer <command> [<args>]

Hello @ktinthecloud

there is an error in the last PR #131 who add based64encode example, i just fix it with #134

you need to have

user_data         = base64encode(file("cloud-config-ubuntu.yaml"))

in your case you get the name of the file in the user_data not the content
