Bugs with permissions?

[juju4]

Hello,

Thanks a lot for your work but I have issues to make it work I'm using vagrant 1.7.4 and image ubuntu/trusty64 for virtualbox

I get following output

with the corresponding configuration in site.yml alone or with other roles

Any help?

Thanks

Hi!

Sorry for the late answer.

IMHO syslog-ng tries to test the generated configuration but in your case it's a directory (/home/vagrant/.ansible/tmp/ansible-tmp-1438458690.15-193309305713974/source). I would expect to see a syslog-ng.conf file here.

Yes, I was supposing that. but at this step, I can't understand why for now

TASK: [ihrwein.syslog-ng | applying client mode configuration if the generated syntax is OK] *** 
failed: [csyslog] => {"failed": true}
msg: failed to validate: rc:1 error:Error opening configuration file; filename='/home/vagrant/.ansible/tmp/ansible-tmp-1439598047.28-258004396674643/source', error='Permission denied (13)'

this line is just a template command as root, there should not be any permission denied It seems to be the temporary file which is validated by syslog-ng but fails

so it means the validation is not working but

$ syslog-ng --syntax-only --cfgfile syslog-ng.conf.0 
syslog-ng: Error setting capabilities, capability management disabled; error='Operation not permitted'
$ sudo syslog-ng --syntax-only --cfgfile syslog-ng.conf.0 
$

it runs as root but have a permission denied...

If I disable validate options in tasks/main.yml, it is working

seems similar to https://github.com/ansible/ansible/issues/7553

+1 as I am also experiencing this on a vanilla Ubuntu box
