Apt Operations

Manage apt packages and repositories.

Facts used in these operations: apt.AptKeys, apt.AptSources, server.Date, deb.DebPackage, deb.DebPackages, files.File, gpg.GpgKey.

apt.deb

Add/remove .deb file packages.

apt.deb(src, present=True, force=False)
  • src: filename or URL of the .deb file
  • present: whether or not the package should exist on the system
  • force: whether to force the package install by passing –force-yes to apt
Note:
When installing, apt-get install -f will be run to install any unmet dependencies.
URL sources with present=False:
If the .deb file isn’t downloaded, pyinfra can’t remove any existing package as the file won’t exist until mid-deploy.

Example:

# Note: Assumes wget is installed.
apt.deb(
    name="Install Chrome via deb",
    src="https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb",
)

apt.dist_upgrade

Stateless operation

This operation will always execute commands and is not idempotent.

Updates all apt packages, employing dist-upgrade.

apt.dist_upgrade()

Example:

apt.dist_upgrade(
    name="Upgrade apt packages using dist-upgrade",
)

apt.key

Add apt gpg keys with apt-key.

apt.key(src=None, keyserver=None, keyid=None)
  • src: filename or URL
  • keyserver: URL of keyserver to fetch key from
  • keyid: key ID or list of key IDs when using keyserver
keyserver/id:
These must be provided together.

Examples:

# Note: If using URL, wget is assumed to be installed.
apt.key(
    name="Add the Docker apt gpg key",
    src="https://download.docker.com/linux/ubuntu/gpg",
)

apt.key(
    name="Install VirtualBox key",
    src="https://www.virtualbox.org/download/oracle_vbox_2016.asc",
)

apt.packages

Install/remove/update packages & update apt.

apt.packages(
    packages=None, present=True, latest=False, update=False, cache_time=None, upgrade=False,
    force=False, no_recommends=False, allow_downgrades=False, extra_install_args=None,
    extra_uninstall_args=None,
)
  • packages: list of packages to ensure
  • present: whether the packages should be installed
  • latest: whether to upgrade packages without a specified version
  • update: run apt update before installing packages
  • cache_time: when used with update, cache for this many seconds
  • upgrade: run apt upgrade before installing packages
  • force: whether to force package installs by passing –force-yes to apt
  • no_recommends: don’t install recommended packages
  • allow_downgrades: allow downgrading packages with version (–allow-downgrades)
  • extra_install_args: additional arguments to the apt install command
  • extra_uninstall_args: additional arguments to the apt uninstall command
Versions:
Package versions can be pinned like apt: <pkg>=<version>
Cache time:
When cache_time is set the /var/lib/apt/periodic/update-success-stamp file is touched upon successful update. Some distros already do this (Ubuntu), but others simply leave the periodic directory empty (Debian).

Examples:

# Update package list and install packages
apt.packages(
    name="Install Asterisk and Vim",
    packages=["asterisk", "vim"],
    update=True,
)

# Install the latest versions of packages (always check)
apt.packages(
    name="Install latest Vim",
    packages=["vim"],
    latest=True,
)

# Note: host.get_fact(OsVersion) is the same as `uname -r` (ex: '4.15.0-72-generic')
apt.packages(
    name="Install kernel headers",
    packages=[f"linux-headers-{host.get_fact(OsVersion)}"],
    update=True,
)

apt.ppa

Stateless operation

This operation will always execute commands and is not idempotent.

Add/remove Ubuntu ppa repositories.

apt.ppa(src, present=True)
  • src: the PPA name (full ppa:user/repo format)
  • present: whether it should exist
Note:
requires apt-add-repository on the remote host

Example:

# Note: Assumes software-properties-common is installed.
apt.ppa(
    name="Add the Bitcoin ppa",
    src="ppa:bitcoin/bitcoin",
)

apt.repo

Add/remove apt repositories.

apt.repo(src, present=True, filename=None)
  • src: apt source string eg deb http://X hardy main
  • present: whether the repo should exist on the system
  • filename: optional filename to use /etc/apt/sources.list.d/<filename>.list. By default uses /etc/apt/sources.list.

Example:

apt.repo(
    name="Install VirtualBox repo",
    src="deb https://download.virtualbox.org/virtualbox/debian bionic contrib",
)

apt.update

Stateless operation

This operation will always execute commands unless the cache_time argument is provided.

Updates apt repositories.

apt.update(cache_time=None)
  • cache_time: cache updates for this many seconds

Example:

apt.update(
    name="Update apt repositories",
    cache_time=3600,
)

apt.upgrade

Stateless operation

This operation will always execute commands and is not idempotent.

Upgrades all apt packages.

apt.upgrade()

Example:

apt.upgrade(
    name="Upgrade apt packages",
)
