Download Linux
A Linux Mint download is a bootable ISO image, typically between 2 GB and 5 GB in size, that you save to your computer and burn to a USB drive or DVD to install the operating system on a second machine.
The file arrives as a single archive, usually in .iso format, fetched from the project's official server at mint.com, and it contains the complete root filesystem, the kernel, and every package the installer needs, so no further downloads are required after the transfer finishes. The same pattern applies to the broader family of Linux distros, from Debian and Ubuntu to Arch and Fedora, and it is the pattern this page walks through end to end: where to get the file, how to confirm it arrived intact, and how to write it to media so a target machine will boot from it.
The ISO you pull here is the same artifact a developer installs on a VPS or a bare-metal box before standing up Linux for the LAMP stack, so a clean download-and-verify habit pays off in production as well as on the desktop. The distro choice changes the package manager and the default toolchain, but the three steps on this page, fetch, verify, write, are identical whether the image targets a laptop, a home server, or the nodes that run Server-side web stacks and the Linux systems in a small hosting operation.
Where to download the ISO
Every mainstream distribution publishes its ISOs from a single canonical directory on its own domain, and the download table below lists the 4 primary URLs and the default image each one serves. Sticking to these 4 addresses avoids the mirror sites that repack or rebrand the files and inject adware into the installer.
| Distribution | Official download URL | Default ISO | Approximate size |
|---|---|---|---|
| Debian | debian.org/dt-release/ | Debian 13 "Trixie" netinst | about 4 GB |
| Ubuntu | ubuntu.com/download | Ubuntu 24.04 LTS desktop | about 5.8 GB |
| Linux Mint | mint.com/download | Mint 22 "Wilma" Cinnamon | about 2.9 GB |
| Arch Linux | archlinux.org/download | Arch netinstall | about 850 MB |
Each site also lists a set of 30 to 50 mirror servers, and the file you retrieve is bit-for-bit identical regardless of which mirror you pick, so pick the one with the lowest round-trip latency to your connection. If a mirror is slow or drops the transfer, the next one in the list serves the same byte stream with no re-encoding.
Choosing between desktop, server and lite images
The download page for each distribution splits the ISOs into 3 image families, and the right one depends on what the target hardware will run. The 3 families and their intended roles are:
- Desktop images ship with a graphical environment, a web browser, office tools and a media codec pack; the Ubuntu 24.04 desktop ISO carries the GNOME 46 session and the default snap package store
- Server images strip the GUI and add the 5 core service packages, sshd, systemd-networkd, a firewall manager, the package repository client and a monitoring agent, so the installed footprint sits under 2 GB instead of 4 GB
- Lite and netinstall images carry only a minimal installer and the 3 essential kernel modules, leaving the package selection to a post-install prompt; the Debian netinst and the Arch netinstall both follow this pattern, and a "Linux lite" download is simply the smallest build in that family
For a machine that will host web applications, the server image is the correct starting point: the 2 GB footprint leaves room for 2 to 3 additional service containers or a dedicated database instance before the 16 GB RAM ceiling of a typical small VPS is reached.
Verifying the ISO before you use it
Verification confirms that the file on your disk matches the one the project signed, and it takes 2 steps that together close the 2 most common tampering vectors, a corrupted transfer and a swapped file. The project publishes a SHA-256 checksum for every release in a text file, and the SHA-256 algorithm produces a 64-character hex string, so a single flipped bit in a 3 GB download changes at least half of those 64 characters.
- Fetch the SHA-256SUMS file from the same directory as the ISO and download its GPG signature alongside it
- Run the checksum command for your shell: sha256sum on Linux and macOS, Get-FileHash on Windows PowerShell, and compare the output to the published value
- Verify the GPG signature against the release key the project lists in its keyring, which confirms that the checksum file itself was not altered in transit
If the checksums disagree, delete the file and re-download it from a different mirror; a mismatch on 2 separate mirrors means the published checksum is stale, not that your copy is corrupt. The GPG step matters most when the checksum page is served over a CDN that you do not control, because the signature binds the hash to a specific keypair that the project rotates on a fixed 2-year cycle.
Writing the ISO to a USB drive
Writing the ISO to a USB drive turns the file into a bootable volume that the target machine's UEFI firmware can read at power-on, and the process overwrites everything on the stick, so use a drive with at least 8 GB of capacity and no files you need to keep. The 2 tools below cover every mainstream operating system and both produce a byte-exact copy of the ISO onto the device.
- dd on Linux and macOS: run dd if=/path/to/image.iso of=/dev/sdX bs=4M status=progress, where sdX is the target device, and wait for the 100 percent completion line before syncing
- Rufus or Ventoy on Windows: Rufus writes a single ISO in 2 to 4 minutes on a USB 3.0 stick, while Ventoy lets you load multiple ISOs onto one drive and boot any of them from a small menu
After the write finishes, re-read the drive with the same checksum tool and compare the hash to the original; a matching 64-character value means the drive will boot exactly as the project intended. If the target machine uses a legacy BIOS instead of UEFI, check that the ISO image you chose carries an isohybrid partition table, which every mainstream distribution has shipped since the 2019 release cycle.
After the install: the first 20 minutes on a fresh system
The install process ends with a reboot, and the 20 minutes after that reboot set the baseline for every package, service and security patch the system will receive for the rest of its life. The 4 tasks below, in order, take roughly 10 minutes on a wired connection and close the largest gap between a factory-default install and a box that is safe to point a public IP address at.
- Update the package index and apply every available security patch with the distribution's native command: apt on Debian and its derivatives, dnf on Fedora and the RHEL family, pacman on Arch
- Create a non-root user with a 16-character passphrase and add it to the sudo or wheel group, then disable direct root login in the SSH daemon configuration
- Enable the host firewall, ufw on Debian-based systems or firewalld on the RHEL family, and allow only the 2 ports the server actually serves, port 80 for HTTP and port 443 for HTTPS
- Set the timezone, the NTP source and the hostname to values that match the rest of the infrastructure, so log timestamps line up across the 3 or 4 machines in a small cluster
After those 4 steps the system is a working baseline: the package manager knows about 50,000 or more packages in the configured repositories, the firewall rejects unsolicited inbound traffic on every port except the 2 you opened, and the SSH service accepts only key-based or strong-passphrase logins. From there the work branches into the specific services you plan to run, but the ISO download, the checksum verification and the USB write are done, and the machine is yours to configure.
