Cannot deploy after trellis update

jillii · August 10, 2021, 4:00pm

Hi,

I’ve been having trouble getting my site back to normal after updating trellis. It seems like one thing leads to another…

Right now, I’m having trouble deploying changes to the site. When I run ./bin/deploy.sh staging mysitename.com I get an error (the error message changes depending on which version of ansible I have - I’ve tried 2.9, 2.10, 2. 5, 4. 3, 2.3, and a few others). The deployment doesn’t run at all. I’ve tried installing different versions of ansible using pip, as well as apt (one thing to note - running ansible --version with version greater than 2.7 returns the error below, even though pip installs successfully).

I can deploy my other sites, with old versions of trellis, without an issue.

Linux mint cinnamon 3.8.8
Wordpress 5.8

Thanks for reading!

Jill

PS Here’s a list of a errors received using various versions of ansible:

ansible 4.3

./bin/deploy.sh: line 45: ansible-playbook: command not found

ansible 2.10

./bin/deploy.sh: line 45: ansible-playbook: command not found

ansible 2.9

ERROR! Unexpected Exception, this is probably a bug: cannot import name AnsibleCollectionLoader
the full traceback was:

ansible 2.4

And this is the error I’m seeing after running ansible --version when using ansible versions 2.8 or greater:

ERROR! Unexpected Exception, this is probably a bug: cannot import name AnsibleCollectionLoader
the full traceback was:

Update: I fixed the issue where my computer isn’t recognizing ansible (for ansible version <= 2.7). The primary problem persists.

Do you still get ansible-related errors or errors concerning the provisioning of the target system?

jillii · August 10, 2021, 5:23pm

I get the same errors as mentioned in my original post

strarsis · August 10, 2021, 5:24pm

What kind of system is this? Linux, Ubuntu/Debian; OS X; WSL 1/2?
Are you using pip as root or as normal user?
Does the pip installation of ansible run through without errors?
What python version are you using?
Sometimes ansible is installed on different python versions.

jillii · August 10, 2021, 5:27pm

Thanks for your help. I’m running Linux mint cinnamon 3.8.8, using pip as super user, pip runs without errors,
Python 2.7, pip 19.2.3.

Would a simple ansible --version work?

jillii · August 10, 2021, 5:31pm

It works until ansible version 2.8 (good question - I edited my comment above to reflect that).

strarsis · August 10, 2021, 5:36pm

What does which ansible command say for a non-working ansible version, and what path does it print for a working one?

How are you installing these ansible versions using pip - what is the exact command and what is the output?

jillii · August 10, 2021, 5:42pm

which ansible returns /usr/local/bin/ansible for ansible version 2.8 (for which ansible --version would return an error).

I just change the ansible version using sudo pip install ansible==X.X

Here’s the full output of updating ansible 2.7 to 2.8:

jill@jill-Inspiron-7373:~/Sites/sitename/trellis$ sudo pip install ansible==2.8

You could first uninstall all ansible packages on that workstation, including one potentially being installed by a package manager (e.g. apt) instead. In the end no ansible command should be found anymore.
For being sure that everything can be re-installed cleanly, you can use the pip-autoremove tool.

Then re-install an ansible version that hadn’t worked before and hopefully it is cleanly installed.

That fixed my issue. Thank you for your help!
