apt call always returns changed

[Francisco Reyes]

I have this in a playbook

- name: Install needed packages

    apt: pkg={{ item }} state=latest

    with_items:

    - libxml2-dev

    - libxslt-dev

    - memcached

    - uwsgi

Every single time it runs, it reports changed... 

output with -vvvv

Any ideas why it keeps reporting "changed". 

I tried checking if apt upgrade even reports anything in the target machine and it doesn't.

I can see same behaviour for following play which is quite similar

# TODO: This is marked as changed even if no package is installed
- name: Install dev ubuntu packages for jenkins
  sudo: yes
  apt:
    pkg={{item}}
    state=present
  with_items: ['libxml2-dev', 'libxslt-dev', 'zlib1g-dev']
  tags: install

funny thing is that it doesn't happen for other packages. only for these 3.

After some troubleshooting problem looks to be in libxslt-dev package

So I'm sorry for spaming but I cracked it problem is that there is no package called libxslt-dev that's just an alias to libxslt1-dev and if you use former name it will print a node to stdout. Which will trigger the change.

opsci:~ $ sudo apt-get install libxslt-dev
Reading package lists... Done

Note, selecting 'libxslt1-dev' instead of 'libxslt-dev' <<<< note

libxslt1-dev is already the newest version.

0 upgraded, 0 newly installed, 0 to remove and 65 not upgraded.

libxslt1-dev is already the newest version.

this happens with virtual packages, as they do not appear as
installed, but then when apt runs the package that provides the
virtual slot is found and no change is made, but it was detected as
such.
