Ansible-Vault Error: Unexpected Exception: integer division or modulo by zero

[Victor Keenan]

When creating an Ansible vault with:

 

ansible-vault create test.yml

I receive the following error:

  

Unexpected Exception: integer division or modulo by zero

Does anyone have any tips on resolving this? Thanks for the help in advance!

[Brian Coca]

what version are you using? there was a bug that caused this but it
has been fixed. Also output with -vvvv would be helfpul

Thanks Brian for the help! I'm using ansible 2.1.0 (devel 5e18bc5955). My -vvvv output is...

Unexpected Exception: integer division or modulo by

zero
the full traceback was:

are you trying to edit a non existant file?

It works on Ubuntu for me too. Just not on Mac OS X.

[Matt Martz]

What contents are you putting in the vault file?  I can get this to happen if I put nothing in the file.  In which case the following is the cause:

  File "/Users/matt/python_venvs/ansibledev/ansible/lib/ansible/parsing/vault/__init__.py", line 249, in _shred_file_custom

    for _ in range(0, file_len // chunk_len):

ZeroDivisionError: integer division or modulo by zero

But is this happening if you put content into the file?

We should probably solve the above error regardless.

Also, what EDITOR is being used on Ubuntu and Mac?  Are they both vim? What versions?

Hi Matt, thanks for the help!

I'm creating a blank file to add content. I thought the process was use

ansible-vault create filename.yml

and then it opens in your default editor to add content. Mine is Vim 7.3. I'm getting the error on create.

If I have an existing file with content already and use

ansible-vault encrypt filename.yml

it works fine. So does the decrypt command.

I think I understand the issue, and based on my experimentation I have created an issue which you can find at https://github.com/ansible/ansible/issues/14055
