I was trying to clean cache by using "yum cleanall" command after that i tried yum update, but it is ging fallowing error
bash-4.1# yum update
Loaded plugins: fastestmirror, refresh-packagekit
Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://mirrorlist.centos.org/?releas...h=i386&repo=os
14: PYCURL ERROR 22 - "The requested URL returned error: 407"
Error: Cannot find a valid baseurl for repo: base
The 407 error seems like network problem.
I had http proxy problem earlier but i solved it then by including username and password in "yum.conf"
and also included env variable as fallows
i am not able to understand this new problem,i found that the folders in var/cache/yum were empty i think yum cleanall command might have deleated all the files related to yum .
can any one please explain what is the actual reason for yum not working in my case.
