Description

Most Linux distributions use a kernel package to easily allow upgrading it when bugs or security flaws were found. This test determines the number of installed packages.

How to solve

While it is fine to have a few kernel packages installed, the number should typically not be above 5 installed versions of the kernel package. Remove older versions to keep both the file system and boot loader clean.
