yum update not working

[rev.dennis 7]

For some reason when I run

yum update

I am getting a load of errors and it fails.

Did you try?

yum clean all

it looks like you may have a repository issue.

Make sure yum isn't trying to go through a proxy that isn't there

sudo cat /etc/yum.conf

Okay today, having a bad day.  Tried to do an yum update and it locked out my user account. 

dhosang@usdet1lvdwb001:$ sudo yum update -y

The above is definitely cut down from the pages long of Proxy Authentication Required error messages that eventually locks my account out.

So once I unlocked the account that is displayed when I type echo $http_proxy I do a quick test to see if I have internet access by running:

dhosang@usdet1lvdwb001:$ curl -I https://thezah.com

All that is really important is that you got HTTP/1.1 200 OK

So what's next.. you proved that you can get to the internet fine but your yum update or yum upgrade is failing proxy authentication.

Try doing a search for something like wireshark

dhosang@usdet1lvdwb001:~$ sudo yum search wireshark

This clearly shows that yum is getting through the proxy...  but wait, you still are getting proxy authentication errors when trying to do a yum update?
