Fedora 15 yum not working

[anishgeorge]

hello, I just installed F15. when i try first time "yum update" the result was :

" Error: Cannot retrieve repository metadata (repomd.xml) for repository: fedora. Please verify its path and try again"

To resolve this, I tried,
1. setting proxy in network settings.
2. In .bashrc ->

export http_proxy=uname: pass#at#host: port

3. In yum.conf

proxy=host: port
proxy_username=uname
proxy_password=pass

4. commented mirrorurl and uncomment baseurl at /etc/yum.repos.d/*
5.

yum clean all

6.

rm -f /var/lib/rpm/ __db*
rpm --rebuilddb
yum check-update

Nothing is working. Still the same error... Any Idea???

NB: My network is working fine.

SOLVED:

The problem solved. There was an '@' symbol in my uname. I changed it and now yum is working good. :dance:

thanks everybody.
