How to solve intermittent Ansible issues? -

-

i sure @ point or must have faced situation 1 unable install package via ansible same thing done logging machine , doing so. intermittent persistent. why so? because once in while might happen package refuses installed throuwing error like

failed: [10.12.10.57] => {"failed": true, "parsed": false} become-success-yqymkgrsndxbhkcnyfjgvzrxvoxpmads traceback (most recent call last):   file "/home/ubuntu/.ansible/tmp/ansible-tmp-1461058305.77-7941776655744/apt", line 2258, in <module>     main()   file "/home/ubuntu/.ansible/tmp/ansible-tmp-1461058305.77-7941776655744/apt", line 554, in main     cache = apt.cache()   file "/usr/lib/python2.7/dist-packages/apt/cache.py", line 107, in __init__     self.open(progress)   file "/usr/lib/python2.7/dist-packages/apt/cache.py", line 151, in open     self._cache = apt_pkg.cache(progress) systemerror: e:unable parse package file /var/lib/apt/lists/us-west-2.ec2.archive.ubuntu.com_ubuntu_dists_trusty-updates_main_i18n_translation-en (1), e:the package lists or status file not parsed or opened. openssh_6.6.1, openssl 1.0.1f 6 jan 2014 debug1: reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: applying options * debug1: auto-mux: trying existing master debug1: mux_client_request_session: master session id: 2 shared connection 10.12.10.57 closed.

you can run play again , again won't go away, once inside machine , apt-get update , goes away though machine updated. happens in 1 out of 100 cases , occur, unable figure out why?

it fact you're trying run playbook after ec2 instance started? have feeling other client (say system) locking apt directory. if case, wait until server started. can take /var/log/cloud-init-output.log see box when it's starting (you'll see apt-get outputs there).

when happens again, try find if reason removing lock files like:

sudo rm /var/lib/apt/lists/lock sudo rm /var/cache/apt/archives/lock

and run playbook again. if succeeds, point problem. in addition, if find problem due playbook runs soon, might want consider add delay explained here: http://docs.ansible.com/ansible/wait_for_module.html or other kind of event catcher determine if system ready used.
