module: apt_repository
short_description: Manages apt repositores
description:
2012-11-21 18:49:30 +01:00
- Manages apt repositories (such as for Debian/Ubuntu).
version_added: "0.7"
options:
repo:
description:
- The repository name/value
required: true
default: null
state:
description:
- The repository state
required: false
default: present
choices: [ "present", "absent" ]
notes:
2012-11-21 18:49:30 +01:00
- This module works on Debian and Ubuntu only and requires C(apt-add-repository) be available on the destination server. To ensure this package is available use the M(apt) module and install the C(python-software-properties) package before using this module.
2012-10-17 00:17:44 +02:00
- This module cannot be used on Debian Squeeze (Version 6) as there is no C(add-apt-repository) in C(python-software-properties)
2012-10-03 04:32:17 +02:00
- A bug in C(apt-add-repository) always adds C(deb) and C(deb-src) types for repositories (see the issue on Launchpad U(https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/987264)), if a repo doesn't have source information (eg MongoDB repo from 10gen) the system will fail while updating repositories.
