How safe is it if I run the suggested command line. Is there a bug?

The following packages were automatically installed and are no longer required:

  linux-headers-4.15.0-32 linux-headers-4.15.0-32-generic
  linux-headers-4.15.0-33 linux-headers-4.15.0-33-generic
  linux-headers-4.15.0-34 linux-headers-4.15.0-34-generic
  linux-image-4.15.0-32-generic linux-image-4.15.0-33-generic
  linux-image-4.15.0-34-generic linux-modules-4.15.0-32-generic
  linux-modules-4.15.0-33-generic linux-modules-4.15.0-34-generic
  linux-modules-extra-4.15.0-32-generic linux-modules-extra-4.15.0-33-generic

Use 'sudo apt autoremove' to remove them.

Those are old kernels and headers that APT identified as not being used so it suggested removal.

It's safe to use sudo apt autoremove to cleanup orphaned packages.


Generally its totally safe, Ubuntu do "house cleanup" after installation of newer version of kernel by removing all outdaten version prior one you running currently.

If you want to be 100% safe you can wait for reboot, after which you will have latest version of kernel running and then run "sudo apt autoremove" to remove not needed kernels.

In general there is NO point of having multiple version of kernel except you run in problems with your specific hardware with some (latest) kernels.
