yum (업데이트가 않되는거 같습니다)

안녕하세요

YUM 업데이트가 않되는거 같습니다

운영체제는 페도라3 2.6.9-1.667 입니다

rpm으로 yum 설치되어져 있습니다

yum-2.1.11-3

/etc/yum.conf 파일 내용 입니다

[root@root www]# cat /etc/yum.conf
[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
retries=20
obsoletes=1

# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

이제 업데이트 해보았는데

[root@root www]# yum -y update

You have enabled checking of packages via GPG keys. This is a good thing.
However, you do not have any GPG public keys installed. You need to download
the keys for packages you wish to install and install them.
You can do that by running the command:
    rpm --import public.gpg.key
For more information contact your distribution or package provider.

GPG key 다운 받으라고 나오는거 같은데? 무슨 말인지 모르겠습니다

업데이트 않된거 맞져?

답변 기다리겠습니다 안녕히계세요
