[SOLVED] Reinstall rhn-client-tools with non working yum

Issue

For every yum command it will return SSL certificate error

Loaded plugins: fastestmirror, rhnplugin, security
The SSL certificate failed verification.

My SSL cert if valid.

I checked rhel site for https://access.redhat.com/solutions/93313 but the problem is i cannot reinstall rhn-client-tools since yum is actually not working and for some other reasons i cannot boot it from DVD/image.

Any tips on this?

Solution

Before trying to reinstall, have you also checked your firewall settings and the time and date setting on your server ?

If the firewall is not the issue, I would suggest a simpler approach, just by going to RH's site and downloading the appropriate rhn-client-tools RPM package, copying it to your server and installing it.

"What about the possible dependencies?" I foresee you asking...

• 1. Use a different server (or VM) with the same OS version that has access to the internet.
• 2. use yum with the download only plugin to only download all the needed dependencies (you must have the yum-plugin-downloadonly package installed beforehand) in a local directory like so: yum install --downloadonly --downloaddir=<directory> <package>
• 3. Copy the packages downloaded at step #2 to your affected machine and install them using the rpm utility as so: rpm -ivh /path/to/yum/download/dir/*
