Prevent Automatic Updates

It is also possible to prevent our curated images from automatically updating certain packages or completely.

Preventing Automatic Updates of some packages

It is possible to version lock certain packages you care about by changing the owner of /etc/yum/pluginconf.d/versionlock.list:

sudo chown your-username /etc/yum/pluginconf.d/versionlock.list

Then add any packages to the above file in the same format as the other entries.

Preventing Automatic Updates completely

This is not recommended and must only be done with the express written consent of the Cloud team. This can be obtained by emailing

You still must comply with our terms of service.

Auto updating can be disabled by creating a file at /etc/noquattor. This file should contain the date the file is created and who created it.
