Uninstall problematic patches

Sometimes, the patches published by software vendors do not work correctly, which can lead to serious problems. This can be avoided by selecting a small number of test computers prior to deploying a patch across the entire network. In addition to this, Cytomic Patch also enables you to remove (roll back) installed patches.

Linux and macOS do not support patch uninstallation.

Requirements for uninstalling an installed patch

  • You must have the Install/Uninstall patches permission enabled. See Install, uninstall, and exclude patches for more information.

  • The patch must have been successfully installed.

  • The patch must support the rollback feature. Not all patches support this feature.

Uninstalling a patch

  • Go to the patch uninstallation page. There are three ways to do this:

    • Go to the Status menu at the top of the console. Click My lists - Add in the side panel. Select Installation history

    • Go to the Tasks menu at the top of the console. Select the task that installed the patch you want to uninstall. Click the View installed patches link in the upper-right corner of the page.

    • Access the Last patch installation tasks widget. To do this, go to the Status menu at the top of the console and select Cytomic Patch from the side menu. Click Installation history.

  • From the list displayed, select the patch you want to uninstall.

  • If the patch can be removed, the Uninstall the patch button is displayed. Click the button. The computer selection window appears.

    • Select Uninstall from all computers to remove the patch from all computers on the network.

    • Select Uninstall from "{{hostName}}" only to remove the patch from the selected computer only.

  • Cytomic Patch creates an immediate execution task to uninstall the patch.

  • If a restart is required to finish uninstalling the patch, the solution waits for the user to restart it manually.

An uninstalled patch is displayed again in the list of available patches unless it is excluded. If a scheduled patch installation task has been configured and the patch has not been excluded, it will be reinstalled on the next execution. However, if a patch is withdrawn by the corresponding vendor, it will no longer be shown or installed. See Exclude patches for all or certain computers for more information.
