How To Disable Snap Permanently on Your Ubuntu

Portable software packaging in Linux is now emerging. There are, at least three most popular portable software packages in Linux: AppImage, Flatpak, and Snap.

Beside the security promised by the technology, based on my experience, those portable packages are still far from mature, especially the speed.

Unfortunately, Ubuntu is pushing Snap as the default alternate package manager beside APT. There are basic apps now delivered as snap by default: Chromium and Firefox.

If you prefer APT, you could disable Snap permanently from your Ubuntu system. Here are the steps to get rid snap from your Ubuntu:

1. Uninstal snap

sudo apt-get purge snapd*

2. Disable snap in apt preferences

Use your favorite text editor:

sudo gedit /etc/apt/preferences.d/nosnap.pref

Put this line of codes:

Package: snapd
Pin: release a=*
Pin-Priority: -10

Save the file.

3. Update apt

sudo apt update

Now, everytime you try to install a package related or depends on snap, you will get an error. Alternatively, you have to use other DEB repository, such as PPA.

4. Re-enable snap

If you want to re-enable snap, simply delete the preference file:

sudo rm /etc/apt/preferences.d/nosnap.pref

sudo apt update

Ubuntu Kylin 19.04 Review : A Gorgeous Windows 10 Clone

It's been quite a while since the last post I wrote in this blog. My daily life prevents me to write another stuff about Linux Desktop, and now I'm curious to take a look to the Ubuntu Kylin 19.04. Ubuntu is always be my favorite distro. It supports huge number of hardwares, it has probably the largest Linux software repository. It is also --the most important thing-- very easy to install, even for beginners. But for some couple of years, because of technical reason, I stopped to play around with the Ubuntu releases. I stood for KDE Neon and became my primary OS because of its simplicity and the look. Few days ago Ubuntu has released its newer version, Ubuntu 19.04 codenamed Disco Dingo. I'm yes impressed by the progress Ubuntu developer has made, especially the way they arrange the GNOME desktop to match the Ubuntu theme. But the most interesting flavor of this release is Ubuntu Kylin. It's an official Ubuntu flavor, designed for Chinese People with its own...

How To Speed Up Your KDE Plasma Desktop (KDE4)

KDE is one of the oldest desktop environment in Linux. While GNOME (the other desktop that as old as KDE) is trying to built its own style of user interface, KDE from the beginning seems to mimics the Microsoft Windows' "classic" user interface. Thus, KDE has its own user base, especially for them who still in love with the Windows' philosophy : a simple desktop, with a single taskbar in the bottom, and a start menu in the left. Personally, I love KDE. It's gorgeous and eyecandy. But sometimes, I feel KDE is little bit slow in my older hardwares. So, after some experiences, I've found some tweak how to make KDE Plasma Desktop Runs Faster . 1. Change The Compositing Engine Go to System Settings>Desktop Effect>Advanced , and change the Compositing type from OpenGL 2.0 to XRender. 2.

And the most used device to use broadband connection is USB Modem (GSM/CDMA), and one of the most used brands is Huawei, a world-recognized Chinese manufacture that focuses to produce great networking devices (modems, router etc).
