Goodbye to other packages (rpm & deb), Say Hello to Snaps

We have already discussed about Snap Command Examples brand new package manager for Ubuntu. I got surprise when reading about snaps on Ubuntu insight blog, wow what a fantastic improvement on the Linux environment. We know lot more about snap package with Ubuntu but many of us doesn’t know, now we can install Snap package to other distribution too. Canonical founder Mark Shuttleworth didn’t expect other distro will adapt with snap packages.

Multiple Linux distributions and companies announced collaboration on the “snap” universal Linux package format, enabling a single binary package to work perfectly and securely on any Linux desktop, server, cloud or device.

The community will work with snapcraft.io to provide a single publication mechanism for any software in any Linux environment. Companies are involved as of now Dell, Samsung, the Linux Foundation, The Document Foundation, Krita, Mycroft, Horizon Computing.

Snaps now work natively on Arch, Debian, Fedora, Kubuntu, Lubuntu, Ubuntu GNOME, Ubuntu Kylin, Ubuntu MATE, Ubuntu Unity, and Xubuntu. Other major distro which are currently being validated on CentOS, Elementary, Gentoo, Mint, OpenSUSE, OpenWrt and RHEL, and are easy to enable on other Linux distributions.

As of now 250+ snap packages are available for Ubuntu and i’m listing here few popular packages. Jenkins, OwnCloud, htop, VLC & links.

What’s Snap

Snap packages are secure, isolated from each other and the host system using technologies such as AppArmor, It’s cross-platform, self-contained, allowing a developer to package the exact software their application needs. This sandboxed isolation also improves security and allows applications, and whole snap-based systems, to be rolled back should an issue occur. It has many advantages over the more traditional package formats such as .deb, .rpm, and others. Snaps use a special YAML formatted file named snapcraft.yaml. Snaps really are the future of Linux application packaging.

We have already covered in our previous article, how to install snap on Ubuntu and how to play on it. Just go through the below article to get more experience.

Drawbacks on Snap

  • Snap package size is very high compare with deb package because every Snap packages are bundled with all required libraries and dependencies
  • Have security issue with RPM system because we need to set SELINUX=permissive mode

How to install Snap on Linux

We can install Snap package to few distribution as of now such as Ubuntu, Arch Linux, Debian, Fedora & Gentoo Linux.

$ sudo dnf copr enable zyga/snapcore.
$ sudo dnf install snapd
$ sudo systemctl enable --now snapd.service

Other Universal Packages which you know already, AppImage, Flatpak & OrbitalApps

AppImage : Download AppImage application, make it executable, and run! No need to install, Runs on most 32-bit and 64-bit Linux desktops. No system libraries or system preferences are altered. AppImage is Linux apps that run anywhere and similar to windows & mac application. AppImage work on most Linux Distribution such as RHEL, Fedora, CentOS, Ubuntu, Debian, openSUSE & Arch Linux Systems.

$ sudo wget https://dl.bintray.com/probono/AppImages/Atom-1.7.3-x86_64.AppImage
$ sudo chmod +x Atom-1.7.3-x86_64.AppImage
$ sudo ./Atom-1.7.3-x86_64.AppImag

Flatpak : is the new framework for desktop applications on Linux. It allows the same app to be installed on different Linux distributions, including different versions. And it has been designed from the ground up with security in mind, so that apps are isolated from each other and from the host system. Flatpak work on most Linux Distribution such as Fedora, Ubuntu, Debian, Mageia & Arch Linux Systems.

Orbital Apps : or ORB Apps Open Runnable Bundle came to picture. It’s completely free, open source applications that will help us to RUN more then 60 Apps without installing on system, even you can directly run from USB drive to Ubuntu 16.04 (Currently supported Ubuntu 16.04 & 15.10). Alternatively we can install all the Apps in off-line too (Dependencies are included).
