Bug Description

Binary package hint: apt

apt-get apparently currently uses some simple wget-type sequential download algorithm for all its functions that download anything from the net, like update, install, dist-upgrade, upgrade, build-dep, source etc. This really does not well use the available broadband bandwidth of most users. Hence I am forced to use home-cooked scripts to extract the URLs to download and then pass them to aria2 (GPL) to download, so that the thing is done faster.

Granted, the user may not want his entire bandwidth hogged by apt-get, but at least provide this as an option -- use a faster split-download algorithm, or at least use a good backend downloader like aria2 which provides high-speed downloading.

Thank you for taking the time to make Ubuntu better. Since what you submitted is not really a bug, or a problem, but rather an Feature Request to improve Ubuntu, you are invited to post your idea in Ubuntu Brainstorm at

https://brainstorm.ubuntu.com/

where it can be discussed, voted by the community and reviewed by developers.

Besides, given that it is a Debian package, you should consider posting it upstream to

http://bugs.debian.org/cgi-bin/pkgreport.cgi?src=apt

It is more likely that you will be heard there.

Thanks for taking the time to share your opinion!

Tatsuhiro Tsujikawa, aria2 author, provides a shell script for doing just this. It is MUCH faster.

Seeing as this has been reported upstream and seems like a good idea, I've marked this bug as Triaged.

APT downloads multiple things in parallel if they are from different servers.

Julian, allowing same-host parallel download may introduce the risk of a user actually downloading from same host if a load balancing proxy is not installed. I think Sharma's way is better.

I did not offer any alternative, I just changed the bug title to something matching the request; which clearly is about parallel downloads from one host.
