sudo apt-get update sometimes becomes stucked:
... 99% [Waiting for headers]
This seems to be a common problem and can have several reasons. For example, on one machine, it was caused because I used a bad proxy server configuration.
Is there a way to systematically analyze the problem? It looked at the
man apt-get but could not find any option that provides more information to isolate the problem. Are there any tools besides
apt-get that I can use to get more insights?
