The guide explains why isolated environments are crucial when juggling multiple projects that require different dependency versions and shows how Ubuntu ships a lightweight python3‑venv package to simplify this process.
It walks the reader through creating a project folder, generating a .venv directory with python3 -m venv, activating it with source ./.venv/bin/activate, and then installing packages such as pip, setuptools, wheel, and flask without polluting the system‑wide site‑packages.
The tutorial also highlights common mistakes like running pip outside an activated env, using the wrong Python binary when creating a venv, or unintentionally upgrading global packages, and offers quick sanity checks by listing installed modules inside the environment.
By following these steps, developers can keep their projects isolated, avoid “works on my machine” headaches, and enjoy a cleaner development workflow on Ubuntu 22.04 or 20.04.

LightZone is a classic RAW editor that isn’t in Ubuntu’s default repositories, so this walkthrough shows how to fetch the official .deb file from its GitHub releases or archive and get it running on both 22.04 and 20.04.
After downloading the package with wget you’ll need to resolve older library dependencies, often requiring libqt5core5a and similar packages, by updating apt and using dpkg‑i, looping until all missing bits are satisfied.
Launching LightZone from a terminal or menu will reveal any remaining hiccups such as a missing libgconf-2.so or Qt plugin errors that can be fixed with libgconf-2-4 or qt5-default installs.
While newer tools like Darktable feel heavier, LightZone offers a surprisingly fast workflow and nostalgic filters, making it an attractive lean choice for quick edits on Ubuntu.
This guide walks readers through getting the latest ImageMagick on Ubuntu 22.04 and 20.04, beginning with a quick repo install that supplies version 6.x. It then shows how to move to the newer 7.x release either by adding the official PPA or compiling from source for those who need extra features or custom build flags. The article also explains how installing Ghostscript unlocks PDF conversion and lists common pitfalls such as conflicting binaries, missing delegate libraries, and path issues after a source install. By following these steps users can confidently convert PDFs to PNGs, resize images, and experiment with ImageMagick without the headaches of an outdated package.
The article walks you through installing Redis on Rocky Linux 8 or 9, beginning with system updates and enabling the right repositories from EPEL for EL9 or Remi for EL8. It then covers the actual installation of the redis package, which brings a systemd unit and default configuration file into place, and explains how to tweak that config for binding addresses, passwords, and persistence settings. After starting and enabling the service, the guide shows how to verify functionality with simple redis‑cli commands and offers troubleshooting tips such as SELinux context adjustments and firewall rule additions when exposing the server beyond localhost. Finally it hints at optional steps like TLS encryption for internet‑exposed instances, wrapping up with a concise reminder that a fresh install is ready for caching or pub/sub workloads.
The article shows how to restore Rocky Linux’s missing “firewall-config” GUI on both EL8 and EL9 by installing the necessary packages from EPEL and enabling the firewall daemon. It walks readers through updating the system, ensuring firewalld is installed, adding the epel-release repository, installing firewall-config (and optionally its GNOME‑centric variant), and starting the service so the GUI can connect via DBus. Once launched, users are guided to test a simple rule by enabling HTTP/HTTPS in the Public zone, allowing them to verify connectivity from another machine. Finally, the post warns about common pitfalls such as missing EPEL, not running firewalld, or using root for configuration, and advises keeping only the essential packages to avoid unnecessary clutter.

The guide shows how to install the lightweight Exaile music player on Ubuntu 22.04 and 20.04 via apt, listing prerequisites such as an internet connection and administrative rights. It walks through refreshing the package list, upgrading installed packages, installing Exaile from the Universe repository, verifying the installation with a version check, and even offers a Flatpak alternative for those who want the latest features. The author explains why the native deb package outperforms Snap builds by avoiding duplicated dependencies and slower startup times, and points out a common pitfall of missing GStreamer libraries that can be resolved by installing the base plugin package. After installation users can launch Exaile from the application menu or terminal, import their music library, tweak tags, and enjoy a clean, ad‑free interface.
The article walks readers through a straightforward Kodi installation on Ubuntu 22.04 and 20.04, starting with adding the official PPA to keep the media center up‑to‑date. It then details how to add the repository key, update apt’s package cache, install Kodi itself, and optionally pull in the Qt5 interface for smoother graphics. After launching Kodi, the guide highlights common pitfalls—such as crashes after a driver upgrade or HDMI audio stutters—and offers quick fixes like reinstalling NVIDIA drivers or installing libpulse0. For those who prefer containerized packages, it concludes with a snap‑based installation option that auto‑updates and reduces dependency headaches.
