I've several PPA installed on my system. Every time I perform an apt-get update there's a moment in which the updating process remains stuck in this position (it lasts almost a minute):

Ign precise/main TranslationIndex
Ign precise/main Translation-it
Ign precise/main Translation-en
100% [In lavorazione]

(I don't know in English how the last line is, something like "100% [Working]")

I presume this happens because a download of a PPA is slow. (Do you think this might be the reason?)

If so, I'd like to remove this PPA from my system. The problem is that during this phase I can't distinguish among PPAs because all of them show this URL: precise/main. Is there a way to identify the PPA which is being updated in that particular moment?

Do you really need apt-get update to finish in one minute? On my system it takes about 3-4 minutes, because my internet connection is slow, and I fail to see that it could be disturbing. – Rafał Cieślak Sep 22 '12 at 17:52
I wondered whether there was a way to speed-up the process. If you say that is the physiological time, for me it's ok, it's not disturbing. – Michele Sep 22 '12 at 18:01

Use sudo apt-get -o Debug::Acquire::http=true -o Acquire::Queue-Mode=access update. This enables debugging options to make all HTTP requests sequential and show you every HTTP request going out and response coming back in.

You might comment the referred PPA entry on /etc/apt/sources.list Then do the update again and see if it keeps getting stuck.

Thanks, the problem is that I can't identify the ppa since all of them show the same line while updating: precise/main. – Michele Oct 1 '12 at 10:19
