Frequently asked questions

The questions and answers in this section can help you to better understand Patch for Ubuntu.

What to do when Fixlets fail to install with the following message in the EDR log? "Warning: Nothing to install. Please check if you are using the latest kernel."

This message appears only in case of Fixlets that deploy kernel packages. A kernel Fixlet becomes relevant if the endpoint does not have the target kernel package installed or if the endpoint's active kernel is at a lower version than the target kernel package. An endpoint is still considered subject to kernel vulnerabilities even if it has the latest kernel installed but not using it actively.

To remediate the issue, restart the endpoint and ensure it is using the latest kernel available.

What are Unspecified Fixlets and why do we need them?

Unspecified Fixlets are for the packages found in Ubuntu's security repositories and that do not have a security notice (USN) associated with them. Not all security packages released by Ubuntu have a USN associated with them - Unspecified Fixlets covers such packages.

Which type of Kernel Packages are supported for USN fixlets?

  • linux-image-<version>-generic
  • linux-image-<version>-lowlatency
  • linux-image-<version>-oracle
  • linux-image-<version>-kvm
