apt-fast 1.9

apt-fast is a shell script wrapper for apt-get and aptitude that can drastically improve apt download times by downloading packages in parallel, with multiple connections per package.

Installation

sudo add-apt-repository ppa:apt-fast/stable
sudo apt-get update
sudo apt-get -y install apt-fast

Ubuntu PPA

You can use the Ubuntu PPA to get a graphical configuration file setup and automatic updates, for details see:

• ppa:apt-fast/stable

Debian and derivates

Some distros, such as PCLinuxOS, include apt-fast in their repositories. However, if not included like in Debian or Kali Linux, then the PPA can be manually added by creating a new file /etc/apt/sources.list.d/apt-fast.list:

deb [signed-by=/etc/apt/keyrings/apt-fast.gpg] http://ppa.launchpad.net/apt-fast/stable/ubuntu focal main

To retrieve the signed keys and install apt-fast, execute the following commands as root:

mkdir -p /etc/apt/keyrings
curl -fsSL "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0xBC5934FD3DEBD4DAEA544F791E2824A7F22B44BD" | gpg --dearmor -o /etc/apt/keyrings/apt-fast.gpg
apt-get update
apt-get install apt-fast

Note that the PPA version jammy might need to be updated with the recent Ubuntu LTS codename to stay up-to-date. See the release list for possible LTS codenames to try.

Interaction-free installation

To install apt-fast without interaction, execute the following commands as root after adding the package sources to the sources.list as instructed above:

DEBIAN_FRONTEND=noninteractive apt-get install -y apt-fast

To update specific configuration values, use the debconf command line interface as root, e.g.:

echo debconf apt-fast/maxdownloads string 16 | debconf-set-selections
echo debconf apt-fast/dlflag boolean true | debconf-set-selections
echo debconf apt-fast/aptmanager string apt-get | debconf-set-selections

Quick install

You can quickly install apt-fast by running:

/bin/bash -c "$(curl -sL https://git.io/vokNn)"

Manual

A manual install can be performed as such:

cp apt-fast /usr/local/sbin/
chmod +x /usr/local/sbin/apt-fast
cp apt-fast.conf /etc

You need to have aria2c installed:

apt-get install aria2

Then run apt-fast instead of apt-get or aptitude.

Autocompletion

The completions for the respective shells use the existing apt-get completion. It is required that the apt-get completion be installed. In the case of Bash, the package bash-completion is required. For Zsh and Fish, the required completions are included by default (in their *-common packages).

Bash

apt-get install bash-completion
cp completions/bash/apt-fast /etc/bash_completion.d/
chown root:root /etc/bash_completion.d/apt-fast
. /etc/bash_completion

Zsh

cp completions/zsh/_apt-fast /usr/share/zsh/functions/Completion/Debian/
chown root:root /usr/share/zsh/functions/Completion/Debian/_apt-fast
source /usr/share/zsh/functions/Completion/Debian/_apt-fast

Fish

cp completions/fish/apt-fast.fish /etc/fish/conf.d/completions/
chown root:root /etc/fish/conf.d/completions/apt-fast.fish
source /etc/fish/conf.d/completions/apt-fast.fish

Man page installation

mkdir -p /usr/local/share/man/man8/
cp ./man/apt-fast.8 /usr/local/share/man/man8
gzip -f9 /usr/local/share/man/man8/apt-fast.8
mkdir -p /usr/local/share/man/man5/
cp ./man/apt-fast.conf.5 /usr/local/share/man/man5
gzip -f9 /usr/local/share/man/man5/apt-fast.conf.5

Configuration

The apt-fast configuration file is located at: /etc/apt-fast.conf

Package manager

_APTMGR=apt-get

Change package manager used for installation. Supported are apt-get, aptitude, apt.

Note: When using Linux Mint, don't use apt because the distributor provides a custom shell script with different functionality unsupported by apt-fast.

Confirmation dialog

DOWNLOADBEFORE=true

Set this to any value to suppress the apt-fast confirmation dialog and download packages directly. Leave empty to ask for confirmation. This option doesn't affect package manager confirmation.

Multiple mirrors

Adding multiple mirrors will further speed up downloads and distribute load. Be sure to add mirrors near your location. Official mirror lists:

• Debian: http://www.debian.org/mirror/list
• Ubuntu: https://launchpad.net/ubuntu/+archivemirrors

Then add them to the whitespace- and comma-separated list in the config file, e.g.:

MIRRORS=( 'http://deb.debian.org/debian','http://ftp.debian.org/debian, http://ftp2.de.debian.org/debian, http://ftp.de.debian.org/debian, ftp://ftp.uni-kl.de/debian' )

MIRRORS=( 'http://archive.ubuntu.com/ubuntu, http://de.archive.ubuntu.com/ubuntu, http://ftp.halifax.rwth-aachen.de/ubuntu, http://ftp.uni-kl.de/pub/linux/ubuntu, http://mirror.informatik.uni-mannheim.de/pub/linux/distributions/ubuntu/' )

NOTE: To use any mirrors you may have in sources.list or sources.list.d, you will need to add them to the apt-fast.conf mirror list as well!

Maximum connections

_MAXNUM=5

Set to the maximum number of connections aria2c uses.

Maximum connections per server

_MAXCONPERSRV=10

Set to the maximum number of connections per server aria2c uses.

Maximum connections per file

_SPLITCON=8

Set to the maximum number of connections per file aria2c uses.

File split size

_MINSPLITSZ=1M

Set to the size of each split piece. Possible values: 1M-1024M

Piece selection algorithm

_PIECEALGO=default

Set to the piece selection algorithm to use. Possible values: default, inorder, geom

Downloadmanager file

DLLIST='/tmp/apt-fast.list'

Location of the aria2c input file, used to download the packages with options and checksums.

Downloadmanager command

_DOWNLOADER='aria2c --no-conf -c -j ${_MAXNUM} -x ${_MAXCONPERSRV} -s ${_SPLITCON} -i ${DLLIST} --min-split-size=${_MINSPLITSZ} --stream-piece-selector=${_PIECEALGO} --connect-timeout=600 --timeout=600 -m0'

Change the download manager or add additional options to aria2c.

Proxy

apt-fast uses APT's proxy settings (Acquire::http::proxy, Acquire::https::proxy, Acquire::ftp::proxy) and if those are not available, the environment settings (http_proxy, https_proxy, ftp_proxy). Refer to APT's or the system's documentation.

Download folder

DLDIR='/var/cache/apt/apt-fast'

Directory where apt-fast (temporarily) downloads the packages.

APT archives cache

APTCACHE='/var/cache/apt/archives'

Directory where apt-get and aptitude download packages.

APT authentication

APT_FAST_APT_AUTH=1

Try to authenticate packages from sources that require login.

Verbose output

VERBOSE_OUTPUT=y

Show aria2 download file instead of package listing before download confirmation. Unset to show package listing.

Colors

cGreen='\e[0;32m'
cRed='\e[0;31m'
cBlue='\e[0;34m'
endColor='\e[0m' 

Terminal colors used for dialogs. Refer to ANSI Escape sequences for a list of possible values. Disabled when not using terminal.
