install_image action fails to install EOS image

[getoutofmyyard]

I'm running ztpserver 2.0.0 using a Python 3.8 venv and Apache. The install_image script fails after the image is downloaded. It looks like the script is attempting to pull the file twice from different URLs: http://{ztpserver}:8080/files/images/EOS-4.29.3M.swi and http://{ztpserver}:8080/meta/files/images/EOS-4.29.3M.swi before it fails.

Sanitized output from the Arista switch:

bash-4.2# python zt-download 
...

Sanitized definition file:

actions:
  -
    action: add_config
    always_execute: true
    attributes:
      name: "Push startup configuration to switch"
      url: nodes/{serial}/startup-config

  -
    action: install_image
    always_execute: true
    name: "Validate image"
    attributes:
      url: files/images/EOS-4.29.3M.swi
      version: 4.29.3M

Troubleshooting steps I have tried:

1. Verified the server URL is correct in ztpserver.conf and in dhcpd.conf
2. Verified that the image exists in files/images/
3. Created meta/files/images/ and copied the same EOS image to that location
4. Verified that file/directory permissions are correct
5. Used ztps --validate to validate YAML definition file

396 and #397 should address the reported issue.

We are about to release a new version that should fix this problem.

@getoutofmyyard there's a new v2.0.1 release that should fix this issue
