[Bug 1828200] [NEW] [SRU] kernel package names ending with version without flavor are not matched by generated patterns

[Balint Reczey]

Public bug reported:

Apt ships VersionedKernelPackages regex patterns in
/etc/apt/apt.conf.d/01autoremove from which /etc/kernel/postinst.d/apt-
auto-removal generates kernel package name patterns by appending the
running kernel version including the flavor like
linux-.*-4.15.0-1010-kvm but those generated patterns don't cover
versioned kernel package names including the version without the flavor,
such as linux-kvm-tools-4.15.0-1012.

Unattended-upgrades generates the patterns in a similar way and also
don't cover linux-kvm-tools-4.15.0-1012 and similar packages.

** Affects: unattended-upgrades (Ubuntu)
     Importance: Undecided
         Status: New

** Description changed:

- Apt ships VersionedKernelPackages regex patterns in /etc/apt/apt.conf.d/01autoremove from which /etc/kernel/postinst.d/apt-auto-removal generates kernel package name patterns by appending the running kernel version including the flavor like linux-.*-4.15.0-1010-kvm but those generated patterns don't cover versioned kernel package names including the version without the flavor, such as linux-kvm-tools-4.15.0-1012.
