There are configuration options such as ``apt_get_wrapper`` and ``apt_get_command`` that control how cloud-init invokes apt-get. These configuration options are handled on a per-distro basis, so consult documentation for cloud-init's distro support for instructions on using these config options. .. note:: To ensure that apt configuration is valid yaml, any strings containing special characters, especially ``:`` should be quoted. .. note:: For more information about apt configuration, see the ``Additional apt configuration`` example.a- apt: preserve_sources_list: false disable_suites: - $RELEASE-updates - backports - $RELEASE - mysuite primary: - arches: - amd64 - i386 - default uri: 'http://us.archive.ubuntu.com/ubuntu' search: - 'http://cool.but-sometimes-unreachable.com/ubuntu' - 'http://us.archive.ubuntu.com/ubuntu' search_dns: false - arches: - s390x - arm64 uri: 'http://archive-to-use-for-arm64.example.com/ubuntu' security: - arches: - default search_dns: true sources_list: | deb $MIRROR $RELEASE main restricted deb-src $MIRROR $RELEASE main restricted deb $PRIMARY $RELEASE universe restricted deb $SECURITY $RELEASE-security multiverse debconf_selections: set1: the-package the-package/some-flag boolean true conf: | APT { Get { Assume-Yes 'true'; Fix-Broken 'true'; } } proxy: 'http://[[user][:pass]@]host[:port]/' http_proxy: 'http://[[user][:pass]@]host[:port]/' ftp_proxy: 'ftp://[[user][:pass]@]host[:port]/' https_proxy: 'https://[[user][:pass]@]host[:port]/' sources: source1: keyid: 'keyid' keyserver: 'keyserverurl' source: 'deb [signed-by=$KEY_FILE] http://<url>/ bionic main' source2: source: 'ppa:<ppa-name>' source3: source: 'deb $MIRROR $RELEASE multiverse' key: | ------BEGIN PGP PUBLIC KEY BLOCK------- <key data> ------END PGP PUBLIC KEY BLOCK------- source4: source: 'deb $MIRROR $RELEASE multiverse' append: false key: | ------BEGIN PGP PUBLIC KEY BLOCK------- <key data> ------END PGP PUBLIC KEY BLOCK-------)�id�name�title� description�distros�examples� frequency�activate_by_schema_keys�metaz/var/lib/apt/listsz'/etc/apt/apt.conf.d/94cloud-init-configz)/etc/apt/apt.conf.d/90cloud-init-aptproxyzkeyserver.ubuntu.comz!http://archive.ubuntu.com/ubuntu/z"http://security.ubuntu.com/ubuntu/��PRIMARY�SECURITYz$http://ports.ubuntu.com/ubuntu-ports�amd64�i386)�s390x�arm64�armhf�powerpc�ppc64el�riscv64c C s> | du r t �|�} | tv rt�� S | tv rt�� S td| ��)z�returns the default mirrors for the target.
