I have a problem with Ubuntu 12.04 not allowing me to install installation CD of a modem card. I can't remember the entire error message but it seems like it must be written especially for Ubuntu (Linus) or something like that. I have an older desktop that I have recently installed 12.04 as the sole OS and am now trying to install the modem card for a 56K modem. How can I do this in order to get on the internet. The person I am helping has internet dial up service only.
