Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I know that in order to speed up apt-get downloads, I can use apt-fast (which uses the aria2c or axel engine - it depends on which one I install during the configuration). But even though it says it can pause and resume downloads, I don't know how to do it, and I can't find any answer online that tells me how to do it.

I have no intention of pausing apt-fast update function, I just want the ability to pause the sudo apt-fast install package_name function and resume the downloading of a package in Ubuntu at will using apt-fast (with axel or aria2c)

I have seen in some forums that sudo apt-fast update cannot be paused because it requires starting the entire process. Please correct me if I'm wrong.

Any help would be much appreciated.

Yes, it is not possible to interrupt current downloads smoothly. But if you cancel those downloads with a signal (e.g. pressing ^C) and if you are using aria2 you can easily continue downloading later. Axel does not support continuation of aborted downloads (and is therefore not recommended for apt-fast).

If you have already downloaded some files via aria2 and cancel the download they aren't available for APT until all downloads with apt-fast are finished.

And on the other side if you cancel an apt-get/aptitude/synaptic/etc. download you have to start from scratch with apt-fast. But of course if some packages are already downloaded successfully and therefore are in your archive cache (usually /var/cache/apt/archives) apt-fast will ¨detect¨ them and don't add it to download queue again.
