How can one use or run apt, the Debian family package manager, on here/Arch just to get help/options messages and all information text alike else
if it's going to get solved then how such too for other Linux package man., eg dnf, yum, portage, etc ?
?
One can setup guest Debian (Fedora, Gentoo, etc.) system with virtualization. Or try to build those package managers from sources. But perhaps it would be enough to find and read man pages online?
I have no idea what it is you are trying to do but it is not recommended to have multiple package managers like apt, pacman or zypper on one install. it leads to more clutter and dependency hell.
I suggest you separate those two. I think you might want to look into distrobox. It is in Arch extra repo.
go ahead and destroy your system by installing "apt" and "dpkg: from arch repository. it's a fun experiment.
but if you want a stable system and prefer "apt" interface, just use "aptpac" from aur
p.s. people over in debian and ubuntu are trying to use an "apt" wrapper
Most apt-only packages including most proprietary programs are already on the AUR... and yes if yours by any chance is not there use aptpac or some conversion tool, as guy said above. :)
