Prerequisites
Before getting started, make sure your system is up to date:
sudo apt update && sudo apt upgrade
Back up any important configuration files before making system-level changes. A snapshot or Timeshift backup is always a good idea before major installations.
Step-by-Step Installation
Follow these steps carefully. Each one is tested on the Ubuntu versions listed in the compatibility strip above.
- Update your package index — This ensures you are pulling from the latest repository metadata.
- Install dependencies — Some packages require additional libraries that do not ship with a minimal Ubuntu install.
- Install the main package — Use
aptor the method described below for your specific version. - Verify the installation — Check version numbers and test basic functionality before relying on the setup.
Common Pitfalls
Based on years of community feedback and hands-on testing, watch out for these:
- Not updating first — Running
sudo apt updatebefore installing anything is not optional. Stale package lists cause dependency resolution failures. - Ignoring version compatibility — Instructions written for Ubuntu 12.04 may not apply directly to 22.04. Always check the target version.
- Skipping backups — This sounds obvious, but a quick Timeshift snapshot takes two minutes and can save hours of recovery work.
- Mixing PPAs carelessly — Third-party repositories can conflict with official packages. Add them one at a time and test after each.
