How to install the flash player and Mp3 plugins?
I've recently replaced my hdd, and installed Lucid Lynx, but while setting up my environment I realized that I can't play MP3's or video files.
My computer tries to download plugins, but keeps giving me the following error:
E: Could not get lock /var/cache/apt/archives/lock - open (11: Resource temporarily unavailable) E: Unable to lock the download directory
Someone please help.
