I'm new to Linux, I first installed Red Hat 9, I then found out that it was hard to get updates for that old version of Linux. Someone suggested that I try Fedora. I downloaded and installed Fedora Core 4 and it seemed to be fine until I started looking for updates. I finally gathered up all the packages that I thought I needed and started downloading. I kept getting a message saying that the package didn't have a GPG signature, and do you want to continue? So I just went ahead and continued, when it was all done, the install failed and I clicked on OK and it was gone.
Before I track down these files and try to install them again, I would like to know if this is a good idea. Should I only install packages w/ the GPG signature? Please help, and I thank you in advance.
