I encountered the same issue even though the ca-certificates package is up-to-date  The mirror https   mirrors fedoraproject org  is currently signed by DigiCert High Assurance EV Root CA which is included in my ca-bundle    grep -A 3  DigiCert High   etc ssl certs ca-bundle crt    DigiCert High Assurance EV Root CA -----BEGIN CERTIFICATE----- MIIDxTCCAq2gAwIBAgIQAqxcJmoLQJuPC3nyrkYldzANBgkqhkiG9w0BAQUFADBs MQswCQYDVQQGEwJVUzEVMBMGA1UEChMMRGlnaUNlcnQgSW5jMRkwFwYDVQQLExB3   The reason why https connections failed in my case  was that system date was set to the year 2002 in which the DigiCert High Assurance EV Root CA is not  yet  valid     date Di 1  Jan 11 10 35 CET 2002   Changing the system time fixed the issue

Changing the mirrorlist URL from https to http fixed the issue for me

User · Answer

You may come across this message error  after installing epel-release  The quick fix is to update your SSL certificates   yum -y upgrade ca-certificates   Chances are the above error may also occur while certificate update  if so  just disable the epel repo i e  use the following command   yum -y upgrade ca-certificates --disablerepo epel    Once the certificates will be updated  you ll be able to use yum normally  even the epel repo will work fine  In case you re getting this same error for a different repo  just put it s name against the --disablerepo  lt repo-name gt  flag     Note  use sudo if you re not the root user

Another possible cause is that your architecture is not supported  I ran into this because I was provided with a CentOS VM  wanted to install EPEL and couldn t for the life of me get it done   Turns out the VM was CentOS 7 i386  which is an architecture that is apparently no longer supported by EPEL  I guess the only remedy in this case is to reinstall

Try yum clean all --enablerepo    Then yum update --disablerepo epel

User · Answer

You just needed to update ca-certificates package  Before that just disable all repos with https that are failing  That s why solution with commenting mirrorlist or using http instead https would work also   For example if you need to disable only epel repo   yum --disablerepo epel -y update  ca-certificates   This will also help wget  curl  and anything else that uses SSL certificates
