source /usr/share/zsh/functions/Completion/Debian/_apt-fast

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

To suppress apt-fast confirmation dialog and download packages directly set this to any value. To ask for confirmation, leave empty. This options 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 to your location. Official mirror lists:

Then add them to whitespace and comma separated list in 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 maximum number of connections aria2c uses.

Maximum connections per server

_MAXCONPERSRV=10

Set to maximum number of connections per server aria2c uses.

Maximum connections per file

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.
