How to Create a Flatpak Application from Scratch
Application developers will often choose Flatpak as a medium for packaging and distributing their software. Flatpak allows developers to make their software available across all types of Linux systems without having to publish individual installers to satisfy the requirements of each distribution. App developers can also utilize Flatpak’s distribution system which relies on software repositories; it is rather easy to host your own or upload your work to a renowned Flatpak remote.
How to fix the Error updating application in Flatpak
Flatpak normally does a good job of keeping apps up to date by querying your configured remotes for new versions of installed apps. However, if Flatpak runs into trouble during an update, you may receive the Error updating application message in your terminal. This could occur for a variety of reasons, but usually just means that Flatpak can’t access the remote repository to install a needed update.
Resolving the Dependency not found error in Flatpak
You might receive the Dependency not found error in Flatpak whenever an application that you are trying to run or install has a dependency that can’t be currently found on your Linux system. Ordinarily, Flatpak will automatically download all necessary dependencies when it installs an application, but this does not always work perfectly in practice. The fix for this error usually involves identifying the missing dependency, and then installing it.
Setting Up a Flatpak Remote Repository to Make Installing Apps Easier
Flatpak provides developers and administrators with a lot of flexibility in how they decide to distribute applications. Flatpak can query online repositories (or “remotes”) for software to download and for new updates to already installed applications. Developers can choose to host their own repo and share it with users that wish to download their software, or submit their work to a well known online repo like FlatHub.
How to Create and Publish Flatpak Packages
As an application developer, you may be interested in packaging and distributing your work through Flatpak. Lots of developers choose to use Flatpak because it allows them to deploy their application across a variety of different Linux system, without needing to worry about individual dependencies and differences between distributions. There are also many public software repositories, like FlatHub, where you can upload your work and not need to worry about hosting it yourself.
Solving the Error installing application in Flatpak
The Error installing application response in Flatpak is a generic error message that may occur whenever Flatpak runs into some trouble with installing an application. The most common cause for this type of error is something simple like specifying an application that does not exist, or is not available in any of your configured remote repositories. But this error could also be indicative of more serious problems with Flatpak.
How to install Flatpak on OpenSuse
Flatpak is a third party software deployment and package manager application that can be installed on OpenSUSE Linux or any other major Linux distro. It allows applications to be packaged in a self contained format, which can then be installed and run on any Linux system, without needing to worry about which distribution you are running. One of the biggest benefits of Flatpak is that you can install programs which are not ordinarily available in the default OpenSUSE software repository.
OpenLiteSpeed as reverse proxy
In this tutorial, you will learn how to configure OpenLiteSpeed as a reverse proxy server. A system that sits between a client and a web server (or servers) can be configured as a reverse proxy. The proxy service acts as a frontend and works by handling all incoming client requests and distributing them to the backend web, database, and/or other server(s). The advantages of a reverse proxy become most apparent under high traffic conditions or situations where multiple backend servers are deployed and need some form of load balancing.

QEMU vs VirtualBox: What’s the difference?
Virtualization is a helpful technology that has exploded in popularity and accessibility in the last decade. There are many great reasons to use virtual machines, such as having a test environment separate from your host operating system. It also allows you to run multiple operating systems or Linux distros simultaneously – all inside of their own sandboxed environment, with optional network interconnectivity among your machines.
