[Solved] OpenSSL error: Unable to establish SSL connection

Post by EricLiii » 2018/09/03 08:50:47

I use CentOS 6.5 64bit and have this error: Unable to establish SSL connection. The following are the details.

[root@MyLinuxBox ~]# wget http://people.centos.org/tru/devtools-1 ... s-1.1.repo -O /etc/yum.repos.d/devtools-1.1.repo
--2018-09-03 16:29:49-- http://people.centos.org/tru/devtools-1 ... s-1.1.repo

Unable to establish SSL connection

I have tried 'yum update wget' and '--no-check-certificate', but still have this error. Anyone can help me?
Thanks!

Works fine here on a fully updated CentOS 6.10 server:

Code: Select all

$ wget http://people.centos.org/tru/devtools-1.1/devtools-1.1.repo

Try yum update without any other parameters to update the other packages as well.

There were major changes in openssl at 6.5 and fixes to those changes in almost every CentOS 6 point release since. Update to 6.10 and try again.
CentOS 5 died in March 2017 - migrate NOW!

'yum update' worked! Thank you very much!

The version used in my tutorials is 6.5. So I plan to use 6.5 for now and update later since I have solved this problem by using 'yum update'. Anyway, thank you very much!
