"linux-tools-lowlatency" package fails to update, tries to overwrite files from "linux-tools"

[arturo]

After updating to ubuntu 22.04 I'm getting an error on linux-tools-5.15.0-27-lowlatency trying to install /usr/lib/libcpupower.so.5.15.0-27 which is already installed by linux-tools-5.15.0-27.

The generic version of the package linux-tools-5.15.0-27-generic, doesn't have that file and installs without problem but the lowlatency version seems to erroneously pack that file which leads to a clash with linux-tools-5.15.0-27.

This happens when a low latency kernel is installed without trying to install anything else, just by updating the system.

The specific versions of the packages are:

linux-tools-5.15.0-27-lowlatency: 5.15.0-27.28
linux-tools-5.15.0-27: 5.15.0-27.28

The generic version which works without problem is the same:

linux-tools-5.15.0-27-generic: 5.15.0-27.28

I got this error today:

...

Quick workaround for the above:

$ sudo dpkg -i --force-overwrite /var/cache/apt/archives/linux-tools-5.15.0-37_5.15.0-37.39_amd64.deb

$ sudo apt --fix-broken install

[Piotr Henryk Dabrowski (phd)]

After 6 months it is still happening with:
    linux-tools-5.15.0-50 5.15.0-50.56 and
    linux-lowlatency-tools-5.15.0-50 5.15.0-50.56

This breaks very typical desktop installations (just linux-lowlatency kernel and its tools installed).
Unexperienced users may not know how to fix this problem, rendering their system with not working apt, hence no installations or updates for them.

There is even no "Conflicts" relationship between those packages, which could prevent this buggy behavior.
But in fact both of those packages should be installable.
