NAME
apt-offline - Offline APT Package manager
SYNOPSIS
apt-offline [ARGUMENTS] [OPTIONS]
DESCRIPTION
apt-offline brings offline package management functionality to Debian based system. It can be used to
download packages and its dependencies to be installed later on (or required to update) a disconnected
machine. Packages can be downloaded from a different connected machine.
It can also fetch bug reports for the packages that are downloaded.
Unless the -h/-v or --help/--version options are given, one of the get, set or install commands must be
provided.
set FILENAME [-h] [--install-packages PKG...PKG_N] [--install-src-packages PKG...PKG_N] --src-build-dep
[--release release_name] [--update] [--upgrade] [--upgrade-type upgrade]
set generates a signature file with the data required to install on or update the disconnected machine.
FILENAME {apt-offline.sig} is the signature file generated on the machine. This file will contain all the
information necessary for apt.
--install-packages [PKG...PKG_N]
Packages that need to be installed
--install-src-packages [PKG...PKG_N]
Source packages that need to be installed
--src-build-dep
Download Build Dependency packages for the source packages requested
--release release_name
Release target to install packages from
--apt-backend apt-get
APT backend to use. One of: apt, apt-get, python-apt
--generate-changelog
Generate changelog of the version to be downloaded
--update Generate APT Database signature for an update. This is the equivalent of using apt-get update
--upgrade Generate APT Database signature for package upgrade. This is the equivalent of using apt-get
upgrade
--upgrade-type {upgrade_type}
Type of upgrade you would like to perform. Default is upgrade . Other valid types are dist-
upgrade and dselect-upgrade
Note: If neither of the --update or --upgrade option is explicitly mentioned, the set command will
generate signature for both the --update and --upgrade options.
get FILENAME [-h] [--socket-timeout ] [-d / --download-dir] [-s / --cache-dir] [--no-checksum] [-t /
--threads ] [--bundle] [--bug-reports] [--proxy-host] [--proxy-port]
get downloads APT data as per a signature file.
FILENAME {apt-offline.sig} is the signature file required for details about data to be downloaded. This
file should have been generated by the above set command.
-d, --download-dir DIR_NAME
Download data to the specified DIR_NAME folder. If no folder name is specified, data is
downloaded to a folder in the TEMPDIR path in the format apt-offline-download-$PID
-s, --cache-dir DIR_NAME
Look for data in the cache before downloading it from the internet. If you are on a Debian box,
you would want to specify /var/cache/apt/archives here. If the data is not available in the
cache, the downloaded data is also copied to the cache.
--no-checksum
Enabling this option will bypass the checksum verification of each downloaded file thus losing
integrity of the package. Usage of this option is highly discouraged
-t, --threads NUM_OF_THREADS
Number of threads to spawn for downloads. Default is 1. Using too many threads can overload the
servers, hence it is advisable to keep the number low
--bundle FILENAME
Create an archive file FILENAME. The file is archived in zip format
--bug-reports
Download bug reports for packages that are being downloaded. Currently only the Debian BTS is
supported.
--proxy-host
Specify the Proxy Host to be used.
--proxy-port
Specify the Proxy port number to be used.
install FILE/FOLDER [-h] [--skip-bug-reports ] [--install-src-path PATH] [--allow-unauthenticated]
install installs APT data to the APT package database and updates it.
FILE {archive_bundle_file} Install data from the archive (bundle) file.
FOLDER {/folder/path} Install data from the folder path.
Either FILE or FOLDER argument can be provided to the install command.
--skip-bug-reports
Skip listing of downloaded bug reports, if any.
--skip-changelog
Skip display of changelog, if any.
--allow-unauthenticated
Don't verify GPG signatures for the data to be installed to APT. Usage of this option is highly
discouraged.
--install-src-path PATH
Path to filesystem where we want the source packages to be installed to. Default will be a
folder in your TEMPDIR.
GLOBAL OPTIONS
-h, --help
Show help message
--verbose
Run in verbose mode
--simulate
Developer only. Used for testing.
-v, --version
Display the version of the program
EXAMPLES
NOTE: argument/option handling
apt-offline relies on argparse for argument/option parsing. To explicitly instruct apt-offline
about an argument, you can pass it with the -- delimiter.
Ex. apt-offline set --update --upgrade --install-packages wm2 -- foo.sig
By specifying the -- delimiter, we instruct apt-offline that foo.sig is an argument to the
apt-offline command and not to the --install-packages option.
Otherwise, you could also use it positionally next to the set command
Ex. apt-offline set foo.sig --update --upgrade --install-packages wm2
apt-offline set FILENAME
This command will generate a signature file FILENAME for APT Package Database. To generate only
the signature for updates, use the --update option. To generate only the signature for package
upgrades, use the --upgrade option. Default behavior when no options are specified is to generate
a signature for both the operations.
apt-offline get FILENAME
This command will fetch the data required for APT Package Database as per the signature file
FILENAME generated by apt-offline get. To download bug reports also use the --bug-reports option.
Currently supported bug tracker is Debian BTS only. By default, if neither of -d or --bundle
options are specified, apt-offline downloads data into a folder inside the TEMPDIR environment
folder in the format apt-offline-downloads-PID, where PID is the PID of the running apt-offline
process. Example on a linux machine would be something like: /tmp/apt-offline-downloads-23242/
apt-offline install FILE|FOLDER
This command will sync the data downloaded by apt-offline get to the APT Package Database and
update it. Depending on where the data was downloaded to or packed into, either the absolute
FOLDER path or the archive FILE path can be specified.
NOTE1: On a freshly installed box, that was installed without the network, the package database is
null. In that case, you first need to run apt-offline with just the --update option to ensure you
have a meaningful package database
Example: apt-offline set set.uris --update
NOTE2: On a fresh setup installed through CD/DVD, the default APT setting lists only the install
media URLs. In such case, you need to add the default APT network repositories to the list. For
example, for a fresh (DVD) installed Debian box, add the relevant repository to
/etc/apt/sources.list.d/apt-offline.list or /etc/apt/sources.list
deb http://httpredir.debian.org/debian stable main contrib
(For Debian Stable)
deb http://httpredir.debian.org/debian unstable main contrib
(For Debian Unstable/Sid)
deb http://httpredir.debian.org/debian stretch main contrib
(For Debian Stretch)
deb http://security.debian.org stable/updates main contrib
(Security Updates for Debian Stable)
deb http://security.debian.org testing/updates main contrib
(Security Updates for Debian Testing)
Sequence 1: The following set of commands, when run in sequence, will update a disconnected machine.
apt-offline set update.sig --update
(Generate the required data needed to update the APT database. Should be run on the disconnected
machine)
apt-offline get update.sig --bundle update.zip
(Download the required data needed to update the APT database. Should be run on a machine with
internet connectivity)
apt-offline install update.zip
(Installs the data needed to update the APT database. Should be run on the disconnected machine)
Sequence 2: With successful completion of Sequence 1, the APT database on the disconnected machine will
be up-to-date. Now, the following set of commands, when run in sequence, will upgrade a disconnected
machine.
apt-offline set upgrade.sig --upgrade
(Genereate the required data needed to upgrade the upgradable packages. Should be run on the
disconnected machine)
apt-offline get upgrade.sig --bundle upgrade.zip
(Download the required data needed to upgrade the upgradable packages. Should be run on a machine
with internet connectivity)
apt-offline install upgrade.zip
(Installs the data needed to upgrade the upgradable packages. Should be run on the disconnected
machine)
After successful completion of
Sequence 1 and Sequence 2 in order, further running apt-get upgrade will result in 0 bytes of
additional download.
