Getting 'problem making ssl connection' trying to update yum for EPEL

Post by ttblum » 2019/05/13 17:12:11

Hello,

When I try to update yum I'm getting 'problem making ssl connection' for the EPEL and Extras repos:

Code: Select all

$ yum repolist
Loaded plugins: fastestmirror, security
Setting up Install Process
Loading mirror speeds from cached hostfile
Could not get metalink https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=x86_64 error was
14: problem making ssl connection
 * epel: mirrors.develooper.com
 * extras: repos.lax.quadranet.com
 ...
I changed /etc/yum.repos.d/epel.repo to use the base repos instead of using mirrors:

Code: Select all

/etc/yum.repos.d/epel.repo

[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
That does work:

Code: Select all

 * base: mirror.sfo12.us.leaseweb.net
 * extras: centos.sonn.com
 * updates: mirror.scalabledns.com

repolist: 20,678
However, the URL starts with 'http' (http://download.fedoraproject.org/pub/epel/6/$basearch), so I'm concerned that certificates might not be verified or traffic might not be encrypted.

Does 'baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch' mean that it's going over http?

What's the output from uname -a (please only obscure the hostname portion if you must obscure anything at all) and from rpm -q openssl

Your CentOS is too old to use https URLs from fedoraproject.org. You can work around this by updating your CentOS first; yum update --disablerepo=epel\*

After this is done, yum update should be able to update the EPEL packages you have installed.

Hello,

Does this mean that downloading packages over https is no longer supported on CentoOS 6.x?

If I set 'baseurl=https://download.fedoraproject.org/pub/epel/6/$basearch' in /etc/yum.repos.d/epel.repo I am able to install my packages OK without any errors.

This works:

Code: Select all

/etc/yum.repos.d/epel.repo

[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
baseurl=https://download.fedoraproject.org/pub/epel/6/$basearch
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
Does this mean it's using https?

Code: Select all

$ uname -a
Linux xxxx.yyy.zzz 2.6.32-573.12.1.el6.x86_64 #1 SMP Tue Dec 15 21:19:08 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Code: Select all

$ rpm -q openssl
openssl-1.0.1e-42.el6_7.2.x86_64
I realize Centos 6.x is going to be discontinued in November, but I was hoping to be able to download packages over https for another few months.

Yes, the point is that you haven't run yum update in such a long time that your system is no longer able ot make SSL connections in a secure manner. You need to run yum --disablerepo=\* --enablerepo=base,updates update to get your CentOS itself up to date (currently you are on 6.7 from 2015 and thus missing 4 *years* of security updates and enhancements.

Once that's done and you've rebooted into the new kernel and all the new libraries that were updated, you stand a better chance of it working.

Thanks, after updating to CentOS 6.10 I can use all repos (including EPEL) without any errors.
