I keep getting the following error while running software update after a fresh installtion of Fedora Core 12. I hope I don't need to reinstall it. Normally I would be able to look at the packages and configure what is what, but answers from an expert could cut the amount of time in half because I'm not very familiar with Fedore Core 12. The only line that means anything to me is the repository not found, but it doesn't make sense that Fedora 12 wouldn't be configured to update from regular repositories upon installation.

Here is the error output:

Error Type: <class 'yum.Errors.RepoError'>

What repositories do you have installed?
The trick is to disable those that do not have a public key and to update repos after.

what is a public key? do you personally know of repositories that Fedora Core advocates over repositories that users simply produce whichever material they can. I'm not an open source guru and so I'm hesitant to use software packages that might make my computer insecure. Ubuntu had a lot of fancy names for their repositories, like universal; etc and it would tell you if it was ubuntu staff approved or user submitted; etc. which distribution software was meant for and so-on. I just want to make sure I'm not opening my computer up to the world wide web. Thanks. I hope that was understandable. You might have noticed that I was asking about removing the sudo command in another post just previous to this one, adding repositories is a big reason for that.

I might add that i'm new to Fedora, I only have what remains from class to go on with red hat distros. I opted to encrypt the partitions I installed and its not letting me view my drives when I enter the correct password. What am I doing wrong?

Open a terminal and type

glenn my apologies i'm a pretty addicted computer user, and in the absence of a faster response I just installed Ubuntu. sorry you wasted your time. Althuogh I have written down your terminal entries so that when or if I reinstall fedora and provided the same problem arises I will try this to fix it. thankyou much. note I would have installed fedora again but the cd is mia all of a sudden.
