This quick guide walks you through installing and enabling OpenSSH on Ubuntu 22.04 or 20.04, starting with an `apt update` followed by `apt install openssh-server`. Once the package is installed, you activate the daemon at boot with `systemctl enable --now ssh`, then optionally harden security settings in `/etc/ssh/sshd_config`, such as disabling root login and ensuring pubkey authentication is enabled. The tutorial also covers firewall configuration by allowing the OpenSSH rule in UFW and provides commands to verify that the service is active, including checking status and testing a local SSH connection. Finally, it lists common troubleshooting steps for issues like missing connections, key authentication failures, or unwanted password prompts, so you can resolve typical hiccups quickly.
This guide walks you through installing the Jellyfin media server on Ubuntu 22.04 or 20.04, starting with a clean system update that keeps dependencies current and avoids later headaches. Next it shows how to add the official Jellyfin repository, install the package in one command, enable the service so it boots automatically, and launch the web UI at http://localhost:8096. If you plan to expose your server beyond the LAN, the tutorial covers securing it with Let’s Encrypt, editing the system configuration for HTTPS, and restarting the daemon. Finally, a concise troubleshooting section points out common problems—from missing GStreamer codecs after an upgrade to port conflicts and CPU‑limited transcoding stalls—and suggests quick fixes like installing ubuntu-restricted-extras or moving jobs to a GPU‑enabled machine.
If Ubuntu’s default desktop feels glitchy or heavy, this guide shows how to switch to a lightweight GNOME Flashback session on 22.04 and 20.04.
It explains why the old-style environment can rescue you when driver updates break panels or when older hardware struggles with modern shells.
The instructions walk through updating packages, installing the gnome-session-flashback meta package, adjusting LightDM or GDM configurations if necessary, and then choosing the desired Flashback session at login.
After logging in you’ll see a classic top panel and launcher, with optional compositing via Compiz, giving you a clean, familiar workspace without the bloat of newer GNOME Shell.

The guide walks readers through installing GitLab Community Edition on Ubuntu 22.04 or 20.04, starting with prerequisites such as root access and a minimum of four gigabytes of RAM before performing system updates and installing essential packages like curl, openssh‑server, ca‑certificates, tzdata, and perl. It then shows how to add GitLab’s official APT repository, set the external URL, configure firewall rules for HTTP, HTTPS, and SSH traffic, run `gitlab‑ctl reconfigure` to pull configuration files, start services, and verify access in a browser using the default admin credentials. An optional section explains deploying GitLab with Docker on machines that have less than four gigabytes of memory, while practical troubleshooting tips address common errors such as missing PostgreSQL or Redis services. By following these steps readers will end up with a fully functional, locally hosted GitLab server ready to host projects and run pipelines while also learning how to secure it promptly by changing the admin password.
The guide walks you through setting up Eclipse on Fedora by first checking for a suitable JDK and installing OpenJDK if necessary, which prevents the IDE from failing to start. Next it shows how to grab the correct Linux tarball from eclipse.org, extract it in your home folder, and launch the binary—adding an export for GDK_BACKEND=x11 when Wayland causes display errors. It then explains creating a desktop launcher so Eclipse appears in your menu and remembers workspaces, while also listing common hiccups such as missing libraries or Java runtime detection problems with quick fixes like installing gtk3 or setting JAVA_HOME. Finally, it offers an alternative Flatpak installation for easier upgrades, noting that each update downloads the whole bundle but keeps everything sandboxed.

The guide walks through installing the newest LTS OpenJDK 17 on Ubuntu 22.04 and 20.04 with just a handful of commands and no unnecessary fuss. It explains why modern language features like sealed classes and pattern matching motivate moving from older JDKs such as Java 11, which many build tools still default to. The steps include updating the system, checking for existing Java installations, adding the appropriate PPA on Ubuntu 20.04, installing openjdk-17-jdk, and configuring alternatives so that java 17 becomes the default runtime. Finally, it shows how to verify the install, set JAVA_HOME for Maven, and update IDE SDK settings to avoid lingering references to older JDKs.
