Snap packages are not an Ubuntu-only thing any more. Developers from multiple Linux distributions and companies, including Dell, Samsung, the Linux Foundation and more, announced the collaboration on the snap universal Linux package format, which allow using a single package on any Linux desktop, server, cloud or device.
Right now, snap packages work natively on Ubuntu (with Unity), Kubuntu, Lubuntu, Ubuntu GNOME, Ubuntu Kylin, Ubuntu MATE, and Xubuntu, as well as Arch Linux, Debian, and Fedora. According to the press release, snaps are currently being validated on CentOS, elementary OS, Gentoo, Linux Mint, openSUSE, OpenWrt, and RHEL.
