Updating Red Hat from the command line using Yum
March 3rd, 2009 by Anthony Curreri
Normally, I just:
sudo yum check-update
sudo yum update
sudo rebootNote: A reboot might not be necessary depending on what you are updating.
If yum is having problems resolving some dependencies, or you get the error: “[Errno -1] Metadata file does not match checksum”, try running the command below, then re-running the commands above.
sudo yum clean allIf a “yum clean all” doesn’t fix it, it might be that your satellite server just needs to re-sync with RedHat’s servers. Wait a day and try it again.
If the your system is having trouble communicating with the Red Hat server, you probably need to:
sudo /usr/sbin/rhnreg_ks --force --activationkey=XXXXXXXXXXXXXXXXXXXXFor University of Washington, XXX can be found here.
