For some reason my downloads get stuck and I have no idea why. The upper-right corner icon shows that I am connected to the internet and web pages load normally, but when I try to install something, from Ubuntu Software Center or download anything from the internet, it downloads normally for some time and then gets stuck and says that download speed is "0 kt/s". So, any suggestions on what I should do?

  • Check you Internet speed at speedtest.net/Speedtest.net – Mitch May 26 '12 at 18:14
  • Maybe you are installing packages from synaptic and USC simultaneously , which does not work , since they both access the same database of packages . Try installing from one source ( Ubuntu Software center , Synaptic or from Terminal) at a given time .Please close Synaptic if you are using USC for installing , since it waits for System lock to be released by synaptic.Only one source at a time. – atenz May 26 '12 at 18:31
