YUM dependencies problem

[Borja]

Hello all!

I'm runniing an AMI (Amazon Machine Image) instance (kind of virtual machine) already configured with some programs running on the top of Fedora.

The thing is that when I try to make an update (yum update) som errors come up. I tried to install everything related with libevent*via yum but I can't do it because the dependencie issue described below. I tried aswell to download manually but it didn't work neither.

What could I do to solve this? I thought of uninstalling and installing yum but I'm not sure the consecuences of this. Anything?

Try another mirror, possibly the one of postgresql.org itself.

Other than that: fedora 8 seems wrong.
fedora 17 is the current version.

Mmm...I guess I should upgrade the whole operating system right? Is there anything I sould consider before upgrading?

And last, how can I change the mirror?

Repos are defined in /etc/yum.conf and in newer versions: /etc/yum.repos.d/

Upgrade of the OS means reinstallation.
Typically, these types of data are saved:
- data
- database dumps
- configs
- logs

Note:
A version jump of this magnitude will have consequences.
e.g. data/db dumps might need to be adjusted (think: charsets)
and configs have evolved.
