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 an Arch Linux package with PKGBUILD then install the package with pacman.
Debian/Ubuntu is the most supported Linux distro. Softwares only provide a .deb package for installation is not uncommon:
==> Extracting package data...
==> Fixing possible directories structure differencies...
==> Generating .PKGINFO file...
:: Enter Packager name:
:: Enter package license (you can enter multiple licenses comma separated):
*** Creation of .PKGINFO file in progress. It may take a few minutes, please wait...
==> Checking and generating .INSTALL file (if necessary)...
:: If you want to edit .PKGINFO and .INSTALL files (in this order), press (1) For vi (2) For nano (3) For default editor (4) For a custom editor or any other key to continue:
==> Generating .MTREE file...
==> Creating final package...
==> Package successfully created!
==> Removing leftover files...
