Cannot find a valid baseurl for repo: base --- CentOS 5

Ascendancy5 · 01-06-2009, 07:32 AM

I am running a CentOS 5 server installation, and whenever I go to Applications->Add/Remove Software, I get an "Unable to retrieve software information" error, which is described as:

Code:

Cannot find a valid baseurl for repo: base

I tried editing my CentOS-Base.repo and changing the updates section from a mirrorlist to the baseurl, and I got the same error. I know I am running through a proxy but I do have the proxy set up properly as I can get out to the internet and such... any ideas as to what's going on?

My suggestion might be it's unable to successfully validate the URLs within the base repo. Not sure as to why tho, might be worth copy and pasting the contence of /etc/yum.repos.d/CentOS-Base.repo in here. And I'd suggest encapsulating it within code tags.

Yeah sure, here are the contents of the CentOS-Base.repo file:

Code:

# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.

You can try to specify the proxy URL in /etc/yum.conf. Add the following line in the main section:

Code:

proxy=http://proxy.dummy.org:8080

substituting the proxy address with the actual proxy. Also change the port number if it is other than 8080. If the proxy requires authentication, also add the following:

Code:

proxy_username=user
proxy_password=password

putting the actual username and password, of course.

I added that into my yum.conf and that specific error message went away, but now I'm getting this instead:

Code:

Cannot retrieve repository metadata (repomd.xml) for repository: c5-media. Please verify its path and try again

Not sure if this is good news or bad...

You had the same issue about one month ago. Check it here and follow instructions in post #17. In summary, for some reason you have the CentOS installation DVD enabled as a repository. The error comes out if the DVD is not inserted in the drive. So, edit the file /etc/yum.repos.d/CentOS-Media.repo and change enabled=1 (if this is the case) with enabled=0.

Hey that worked great, thanks for the fix! I know I was having a similar problem before, but I didn't realize it was the exact same problem.. haha, you can tell I'm new. Thanks again for the help!
