  1. I am not able to install wxmaxima. The app is displayed in the software center and also starts installing but in dos not proceed to complete the installation.

  2. What difference it makes when I change the source server (USA,main,Indian) option available in the Ubuntu 16.04?

  • Have you tried sudo apt-get install wxMaxima from the command line? – pietro Jan 24 '17 at 10:13

  • See the above comment and edit the output into your question. 2. That is just the download server where you download from the repositories, pick one close to you (or main if that is slow).

    Welcome to Ask Ubuntu! It is preferred if you can post separate questions instead of combining your questions into one. That way, it helps the people answering your question and also others hunting for atleast one of your questions. Thanks! – guntbert Jan 26 '17 at 18:25
