[SOLVED] Yum attempting to Update/Install Packages - 404 Error Returned.

[klewia]

Hello all, thank you for taking the time to read my post!

Firstly, I am running CentOS 6 as a virtual machine. This Vm/Template came packaged from Nagios and is also behind a proxy in a security sensitive environment.
With the research I have done thus far it seems like my YUM key has fallen out of sync with the EPEL Repository. I have cleared the yum cache, cleared the repo cache as part of my own troubleshooting and have run out of ideas to proceed.


I will produce the output of "yum update" tomorrow when I am in the office. - I have verified that the requests are making it through the proxy (this process stopped working two months ago).

I would welcome suggestions as to how I might gather more logs/information!

Some time ago, the Fedora infrastructure moved the EPEL urls from a (I think) redhat.com address to a fedoraproject.org one. If you edit /etc/yum.repos.d/epel.repo and look at the mirrorlist there, do you see

[code]
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
[/code]

Hi TrevorH,

Thank you for taking the time to reply to this problem! - I have looked at the /etc/yum.repos.d/epel/repo via cat and the output is in the snippet below!

[root@PinnNagios tmp]# cat /etc/yum.repos.d/epel.repo

Try running `yum clean all` then retry. If that fails, is there a proxy server between you and the internet?

[klewia]

Trevor,

I am behind a proxy - I have validated that it is passing traffic. (data/packet analysis tools on the proxy) I also tested this with a sister Centos Server of the same version and confirmed that my proxy settings/compatibility is/are correct.

'Yum clean all' succeeded, the results of 'yum update' is no different than in my previous post I am afraid.

Again, thank you for your time!

[TrevorH]

Try editing /etc/yum.conf and adding

[code]
http_caching=packages
[/code]

[klewia]

Will do, might take me another day to get back to you Trevor - Thanks!

[klewia]

Trevor,

I was able to download & install packages upon entering the http_caching line in yum.conf.

Thank you for your time!

Great, glad I was able to help. Taking the liberty of setting the subject to [SOLVED] as it sounds that way.

thankyou for your input on this TrevorH, your suggestion solved the PYCURL ERROR for me too
