<class 'up2date_client.up2dateErrors.NetworkError'>: Network error:

Resolution

  • Remove the old installed rhn-org-trusted-ssl-cert-1.0-1.noarch.rpm package, if present.
# rpm - e rhn-org-trusted-ssl-cert
  • Download the new rhn-org-trusted-ssl-cert-1.0-1.noarch.rpm package.
# wget <Satellite_FQDN>/pub/rhn-org-trusted-ssl-cert-1.0-1.noarch.rpm --no-check-certificate.
  • Install the new package and then register.
# rpm -ivh rhn-org-trusted-ssl-cert-1.0-1.noarch.rpm

Root Cause

  • System did not have the correct SSL certificate.
  • SSL certificate was corrupted.

Diagnostic Steps

  • Check that system is able to connect to Satellite server.
# telnet satellite.example.com 80
# telnet satellite.example.com 443

  • Confirm if there is a Proxy in between.

  • Register the system without SSL, for this edit the below line in file /etc/sysconfig/rhn/up2date.

serverURL=https://satellite.example.com/XMLRPC

to 

serverURL=http://satellite.example.com/XMLRPC
