I am trying to install two software:

  1. Marble - a software for studying maps and globe and
  2. KPatience - a card game.

Both seem to start the installation nicely but as the download progresses suddenly it stops asking me to check my Internet connection, which is fine. Both these software are part of some KDE package as I understood from their description.

I don't know much about that and I am a new user to Linux. Someone please help me with this problem. I am using Ubuntu 12.04

Did you try downloading after a while? Maybe it was some server side problem. – harisibrahimkv Jul 28 '12 at 6:20
I tried many times after that. Also I tried it again after restarting the system and connection but still no use. – Ani Jul 29 '12 at 3:16
Please paste the messages that asks you to check your Internet connection. A few messages before it too. – harisibrahimkv Jul 29 '12 at 13:13
Got this message while trying to install KPatience again- Failed to download package files-Check your Internet connection.- Details-Failed to fetch… 404 Not Found [IP: 80] – Ani Jul 29 '12 at 14:49
Also, try running "sudo apt-get update" and then installing the packages. – harisibrahimkv Jul 29 '12 at 18:36

Try running sudo apt-get update first and then do the installation.
