update-rc.d: error: unable to read /etc/init.d/clamav-freshclam

[Ralf Mardorf]

PS: There is only one reason why Linux is more stable than Windows. It's
user-responsibility. That's why the pip, snap and 1001 package
management chaos is a step into the wrong direction.

We will soon end up with something Windows kb123452, kb734423 alike that
ends with an error 0x5327454, followed by us running an upgrade
troubleshoot utility that leads to absolutely nothing and after that by
trying to fix the issue by 5 hours following ominous guides for usage
with the systemd-registry, that sometimes fix the issue and sometimes
doesn't fix the issue and the most interesting part is, that error
"0x5327454", does translate to error "something went wrong", so what we
actually will do is following guides to a search "my Linux distro
something went wrong". Apart from ominous systemd-registry guides we
reinstall countless random packages, suggested by the countless random
guides related to "something went wrong (but we don't have got the
slightest idea about what went wrong)".

The only alternative to this would be the iOS/iPadOS way, we install
upgrade 1234, we don't get any information about what is going on and we
can't access anything at all, we even can't share a single file by
several apps, we need to share copies of the same file isntead. If
something went wrong we can turn the computer off and on and we can
reinstall random apps, to no avail. Under the hood it's a POSIX
operating system.

Since Linux isn't a POSIX operating system we will go the Windows way,
not the iOS/iPadOS way, that is hardcore restricted, but more stable
than the Windows way.

At the moment we can still take advantage of reasonably good package
management in the style of DEB, RPM, Gentoo, Arch, Alpine etc., so we
should use the package management and hope that the next upgrade doesn't
install a package named systemd-registry or systemd-kernel.
