Debian/Ubuntu based Linux distros use .deb file to distribute and install packages, but Arch based Linux doesn't have that kind of feature built-in. With tools like debtap, we'll be able to convert a .deb file into Arch Linux package with PKGBUILD then install the package with pacman.
Debian/Ubuntu is the most supported Linux distro, the softwares only provide .deb package for installation are not uncommon:
