I am having some problems with yum.

I am using fedora core 7.

All that follows is using the superuser (su command then all this stuff)

When i try to run "software updater" (aka package updater or pup) i gert an error message: "unable to retrieve software information" with "none" in the etails section.

when i try to run "yum update" i recieve this:

Gathering header information file(s) from server(s)
Server: Red Hat Linux 7 - i386 - Base
Error - /var/cache/yum/base/header.info cannot be found
Please ask your sysadmin to update the headers on this system.

When i try to reinsatll yum, using the command "rpm -ivh home/Andrew/Desktop/yum*" i get this:

Sorry about that big thing but i thought it would be more helpful to have the whole thing.

Can anyone help me with this?

Try an 'rm -fr /var/cache/yum/base' and then run yum update again.

Since you are installing yum 3.2.7 then rpm -ivh home/Andrew/Desktop/yum* should probably be

# rpm -Uvh home/Andrew/Desktop/yum*

But you are better off building the database then getting yum to update itself.

You can put large blocks of code between "code" tags. Then it doesn't loom so much.

Could yo please explain how i would "rebuild the database" i am pretty much a linux noob so i dont know what you mean.

i tried the rm command "your forst instruction" and i got a different error when i ran yum update this time:

When i tried the second thing you said, (the different rpm command option) i got this message:

Error 404 usually means that the page dosn't exist or the server is down.

Heading over to Duke and having a look, I see that http://mirror.dulug.duke.edu/pub/yum-repository/redhat/ only has directories

Parent Directory/ - Directory
7.3/ 2003-Feb-15 16:10:25 - Directory
9/ 2003-Apr-04 00:46:13 - Directory
updates/ 2004-Jan-03 11:12:22 - Directory

i.e. the page doesn't exist. That would explain the error.

Now... here's what is puzzling me: the mirror you've accessed is for Red Hat Linux and not Fedora Core.

Possibly you need to be using the fedora branch?
http://mirror.dulug.duke.edu/pub/fedora ... somthing.

... look to your yum.conf

I tried reinstallind yum using a tar.gz "make, make install" and a whoe binch of stuff came up, now when i run yum update i get this:

Traceback (most recent call last):
