I am running Lubuntu right now and I'm new to Linux. I went to youtube and it said I needed to upgrade Adobe Flash Player and litte window in the to left hand corner came up saying to install plugin needed so I pressed it and then it said no suitable plugins found. So then I Pressed download from Adobe and I just downloded the first thing which was Yum assuming thats the linux version of the plugin I needed. Then I opened the yum download and Archive Manager came up and now I don't know what to do. Help Please
