Hello,
I seek advice everywhere and I am not wise. Does anyone know how to update the applications in Kubuntu 18.04 without a password, please?

See this thread, starting at post #14.

I'm not sure why it would be necessary or wise to to that, but that thread describes the process perfectly ...

Thank you very much for the quick answers. As soon as I wrote my request, I found a solution. Create text file package-manager.pkla in /var/lib/polkit-1/localauthority/50-local.d and reboot.

Insert to file this:

[Install package file]
Identity=unix-group:admin
Action=org.debian.apt.install-file;org.debian.apt.update-cache;org.debian.apt.install-or-remove-packages;org.debian.apt.upgrade-packages

I try sudo visudo, but I don't understand it correctly.
