I was installing openoffice using these commands

 sudo add-apt-repository ppa:upubuntu-com/office
 sudo apt-get update
 sudo apt-get install openoffice

Now after downloading some 20MB my internet connection interrupted when again it tried to install it says as follows

 Err http://ppa.launchpad.net/upubuntu-com/office/ubuntu/ precise/main openoffice amd64 3.4~precise
 Connection failed
 Failed to fetch http://ppa.launchpad.net/upubuntu-com/office/ubuntu/pool/main/o/openoffice/openoffice_3.4~precise_amd64.deb  Connection failed
 E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

how to solve these errors ?
