Disabling Automatic Updates

[grimm08]

Quick question if I wanted to disable automatic updates on my Fedora machines so the students don't brick the computers how would I accomplish this?

Note: I do not want yum to check or download the packages automatically, I wish to do this during scheduled maintenance

Thanks

YUM updates need to be run with root password so if your students have root access you cannot stop them from running updates.

To disabling automatic updates you need to look at your cron and yum-updatesd.

Check cron to see if you have anything setup to rum yum automaticly and stop it.

yum-updatesd is a demon that checks for updates and does what it was configured to do in /etc/yum.

Most updates can be applied without the root password. Sometimes a dependency needs to be downloaded and this is when the root password is needed.

a more barbaric way would to just change the permissions on the yum binary to 700, this will not allow execution to anyone except root
