FLAVOR SELECTION TIP

Understanding Ubuntu Support Lifecycle
Ubuntu’s support model ensures long-term stability for production deployments while offering cutting-edge features through interim releases.
LTS vs Interim Releases
- LTS (Long Term Support) Releases: Enterprise-grade stability
Released: Every 2 years in April | Support: 5 years standard, up to 12 years total
LTS releases receive 5 years of free security updates for packages in the ‘Main’ repository. With Ubuntu Pro (free for personal use on up to 5 machines), coverage extends to 10 years including the ‘Universe’ repository. Legacy Support adds an additional 2 years for a total of 12 years.
- Interim Releases: Latest features and packages
Released: Every 6 months | Support: 9 months
Interim releases introduce new capabilities, updated toolchains, and serve as testing grounds for features that will appear in the next LTS. Popular among developers who need the latest compilers, libraries, and kernels.
Ubuntu Pro and Extended Support
| Support Type | Duration | Coverage | Cost |
|---|---|---|---|
| Standard Support | 5 years | Main repository only | Free |
| Ubuntu Pro | 10 years | Main + Universe repositories | Free (personal, up to 5 machines) |
| Legacy Support | +2 years (12 total) | Extended maintenance | Paid add-on to Ubuntu Pro |
Download Methods and Verification
Ubuntu can be downloaded through multiple methods depending on your internet connection and requirements.
Download Options
- Direct Download: Fastest for stable connections
Best for users with reliable, fast internet connections. Downloads the complete ISO file directly from Ubuntu’s servers or CDN. Typical download sizes range from 2.5 GB to 4.5 GB for desktop editions.- https://releases.ubuntu.com – Official release server
- https://ubuntu.com/download – Main download page
- BitTorrent: Efficient for slower connections
BitTorrent is a peer-to-peer download network that sometimes enables higher download speeds and more reliable downloads of large files. Recommended for slower connections or when downloading multiple ISOs. Helps reduce server load and can resume interrupted downloads.- https://ubuntu.com/download/alternative-downloads – Torrent files and alternative options
- Local Mirrors: Regional alternatives
Ubuntu maintains mirrors worldwide for faster regional downloads. There are 467 mirrors registered for Ubuntu. Select a mirror close to your location for improved download speeds. Useful during high-traffic periods following new releases.- https://launchpad.net/ubuntu/+cdmirrors – CD/ISO image mirrors

Verification Steps
SECURITY NOTICE
Always verify downloaded ISO files before installation to ensure they haven’t been tampered with or corrupted during download. This is especially important when downloading from mirrors or torrents.
Note: This is an example for Ubuntu 24.04.3. Readers should adjust the version numbers and filenames to match their specific ISO download. Release pages for all Ubuntu downloads image versions.
- Download checksums and signature: Get verification files
$ wget -q https://releases.ubuntu.com/24.04.3/SHA256SUMS $ wget -q https://releases.ubuntu.com/24.04.3/SHA256SUMS.gpg
Download both SHA256SUMS and SHA256SUMS.gpg files from the same directory as your ISO.
- Import Ubuntu signing key: Get the official key
$ gpg --keyid-format long --keyserver hkp://keyserver.ubuntu.com --recv-keys 0x843938DF228D22F7B3742BC0D94AA3F0EFE21092
Import Ubuntu CD Image Automatic Signing Key (2012).
- Verify authenticity: Check GPG signature
$ gpg --verify SHA256SUMS.gpg SHA256SUMS
Confirms the SHA256SUMS file is authentic and from Ubuntu. Look for “Good signature” in the output.
- Verify integrity: Check ISO hash
$ sha256sum -c SHA256SUMS 2>/dev/null | grep ubuntu-24.04.3-desktop-amd64.iso
Should output “ubuntu-24.04.3-desktop-amd64.iso: OK” if the hash matches.
Entire verification process of downloaded Ubuntu ISO image.

Installation Media Creation
After downloading your chosen Ubuntu ISO, you’ll need to create installation media.
Creating Bootable USB

Download from: rufus.ie or balena.io/etcher
Both tools provide simple interfaces for creating bootable USB drives. Rufus offers more advanced options while Etcher provides a simpler three-step process.
- On Linux: Use dd command or GNOME Disks
$ sudo dd if=ubuntu.iso of=/dev/sdX bs=4M status=progress
Replace /dev/sdX with your USB device. GNOME Disks provides a graphical alternative with “Restore Disk Image” option.
- On macOS: Use balenaEtcher or dd command
$ sudo dd if=ubuntu.iso of=/dev/rdiskN bs=1m
balenaEtcher provides the easiest method on macOS with automatic drive selection and verification.
