Strange messages

[Klaus Jantzen]

Hi,

I am running emacs 26.1 under Debian Buster on my PC and on my laptop.

On my laptop I get the following messages whenever I open a file:

=====

Warning (emacs): Unable to activate package ‘helm-core’.
Required package ‘emacs-24.4’ is unavailable
Warning (emacs): Unable to activate package ‘helm’.
Required package ‘emacs-24.4’ is unavailable [2 times]

=====

What do I need 'helm'  for?

What do I have to do to not receive these messages anymore?

Thanks for any hints.

K.D.J.
