I’m trying to deploy but seem to get some errors. I have Python 2.7.14.

Command: ansible-playbook server.yml -e env=production

I have Python 2.7.14.

Are you sure?

Name ‘unicode’ is not defined` is a Python 3 error. The output you included has this as well:

[WARNING]: Skipping plugin (/home/User/trellis/example.com/trellis/lib/trellis/plugins/vars/version.py) as it
seems to be invalid: Trellis does not yet support Python 3.6.4. Please use Python 2.7.

Trellis doesn’t support Python 3 yet but it’s being worked on here: Python3 support by swalkinshaw · Pull Request #1031 · roots/trellis · GitHub

ooh, looks like i have 3.6 also installed.

I uninstalled 3.6 now i get

$ ansible-playbook server.yml -e env=production
Traceback (most recent call last):
  File "/usr/bin/ansible-playbook", line 67, in <module>
    import ansible.constants as C
  File "/usr/lib/python3.6/site-packages/ansible/constants.py", line 11, in <module>
    from jinja2 import Template
ImportError: cannot import name 'Template'

This is much more of a Python issue than a Trellis one, and unfortunately we can’t effectively support Python on this forum. I recommend Stack Overflow, or other general support resources for troubleshooting this issue.

I solved that issue with python and now im getting this

Did you solve this issue? I’m hitting this same issue with deploy to my staging environment.

Similar issue trying to provision AWS EC2 instance - Ubuntu 18…
I am running :

$ ansible-playbook server.yml -vvvv -e env=production

Few hours into solving - no luck, so far. Will post if I find a solution.

Edit: Managed to get past EMAC’s issue by removing the bad emacs from /Roles/Defaults/Main.yml
Identified the ones by manually SSHing into my instance and running

$ sshd -T

Then proceeded to remove any un-recognised in “sshd_macs_default:”

!!! But now hitting a wall with letsencrypt <sigh!>
