After I have performed one of
sudo apt-get install eclipse eclipse-cdt g++ procedure I found that Ubuntu is planning to download more than 400Mb and it will take more than 2 hours. It is too long. I also found that it downloads from the US:
Get:21 http://us.archive.ubuntu.com/ubuntu/ trusty-updates/main libservlet3.0-java all 7.0.52-1ubuntu0.3 [294 kB]
I'm in Europe, maybe should I somehow tell Ubuntu to download from a source located closer. How should I do that?
