Knowing exactly which version of the popular Linux Mint distribution you have installed matters for a range of reasons – from ensuring you have the most up-to-date security patches and application support, to technical compatibility planning during development and testing. Especially for developers, Linux Mint version checking should be second nature. This comprehensive guide covers methods for checking your version, parsing version specifics, considerations around updating between releases, and the developer perspective on why Mint‘s version deeply matters.
A Brief History of Linux Mint Releases
Linux Mint has quickly become one of the most widely-used Linux desktop distributions since its first release in 2006 (based on Ubuntu 6.06 LTS). As of April 2022, there have been 21 stable releases of Mint across three major ongoing branches:
| Release | Base Ubuntu Version | Code Name | Supported Until |
|---|---|---|---|
| Mint 21 (Latest) | Ubuntu 22.04 LTS | "Vanessa" | April 2027 |
| Mint 20.3 | Ubuntu 20.04 LTS | "Una" | April 2025 |
| Mint 19.3 | Ubuntu 18.04 LTS | "Tricia" | April 2023 |
Historically, Mint did not always strictly follow Ubuntu‘s LTS release cycle or adopt its version numbering. But a shift occurred with Mint 17.x to synchronize with Ubuntu‘s 5-year support guarantee for extra stability desired by its users.
Notable new features along the way included adjusting desktop environments from GNOME to Canonical‘s Unity and then forking Cinnamon and MATE, multimedia codec and driver investments enhancing Linux‘s out-of-box experience, and by Mint 20 even option for kernel-level system snapshots.
With every release though – from ultra-conservative users clinging to a favored LTS to developers racing to leverage the latest underlying stack – the ability to definitively check a system‘s specific Mint version is crucial.
What Differentiates Mint Releases Under the Hood
While Linux Mint aligns to Ubuntu LTS releases and maintains general application compatibility, under the hood a number of key packages receive Mint or desktop-specific enhancements. And with the Debian base also updating between Ubuntu releases, a cascade effect means notable variances emerge:
-
Kernel: Mint generally opts for the latest Linux kernel available at launch time for hardware support, which often deviates over time from Ubuntu‘s kernel freeze. Almost all Mint 20.x systems should be on 5.4+ for example.
-
Graphics Drivers: Key updates for GPUs (Nvidia, AMD/ATI) and Intel integrated graphics are backported along with selected subsystem upgrades for performance and laptop power savings.
-
Desktop Packages: As the Cinnamon and MATE desktops are exclusive to Mint, their software stacks iterate separately from Ubuntu‘s GNOME focus. From window manager (Muffin, Marco) to theme engines.
So while the base system remains highly similar from a package standpoint to Ubuntu LTS at launch time, under the hood Mint continues to evolve in significant ways tied to its version lifecycle.
Why "Which Linux Mint is This?" Matters for Development
For anyone maintaining software that needs to run seamlessly across Linux Mint releases – especially if distributed directly as debs or targeted towards the Mint ecosystem specifically – clearly identifying the Mint version is crucial for compatibility evaluation. Common scenarios include:
Hardcoded Targets
Sometimes it becomes necessary even in scripts or config files to specify conditional logic based on Linux Mint major version:
# Mint 20+
if [ $(lsb_release -cs) == focal ]; then
# Ubuntu 20.04 base specific logic
fiDependency Issues
A core library required by your application may have substantively changed or be named differently across major Mint releases:
# Broke on upgrade from 18 to 20
apt-get install libgtk-5×Quickly checking the Mint version can uncover these kinds of blockers.
Custom Repositories
You may maintain a portfolio of deb packages compatible only with a narrow Mint version range. Preventing installations on unsupported releases is crucial.
Embedding lsb-release output in repository meta files or displaying warnings during install based on version makes sense.

In test automation, continuous delivery pipelines, and development environments you will want to precisely match production Linux Mint versions. If testing an upgrade process itself, validating specific before and after versions is key.

Given how important the Linux distribution version is for development, what are some best practices for reliably checking and standardizing on the Mint release?
Automatically on Login
For terminal login sessions, edit your shell‘s dotfiles like ~/.bashrc to display the Mint version via lsb_release:
echo "Linux Mint release: $(lsb_release -ds)"Within Code Repositories
Embed the specific Linux Mint release directly into metadata and usage documentation:
Compatible with Linux Mint 20.3 Una and upThrough Structured API Calls
Apps that need to programmatically react to version differences should leverage a dedicated command and parse output – for example:
# Version utility API
$ mintversion --json
{
"release": "20.3",
"codename": "una",
"base": "ubuntu:20.04"
}Via Dedicated Dashboard Views
Build Mint version checking into admin views, displays, and dashboards for your app:
Making the output visible and structured saves users time when troubleshooting.
Analyzing Performance Changes Release-to-Release
An area where analyzing deltas across Mint releases pays huge dividends is comparative performance between versions – whether benchmarking speed improvements in Cinnamon or application load times.
As just one data point, observe how much the file extraction utility 7-Zip gained in throughput speed between 18 and 20 thanks to ongoing updates:
| Release | Compression MB/s | Decompression MB/s |
|---|---|---|
| Mint 18 | 22.6 | 114.7 |
| Mint 19 | 31.5 | 127.3 |
| Mint 20 | 37.4 | 158.1 |
For developers building performance sensitive applications – like games or data science tools – granular metrics like this help set version specific optimization targets.
Community Perspectives Across Generations of Mint
Speaking to application developers, power users, and the Linux Mint community at large – strong opinions certainly emerge around major releases. As bugs arise, changes ruffle feathers, and nostalgia sets in for when X "just worked".
A vocal contingent still run Linux Mint 18.3 or 19 as their daily driver. Die hard fans debate Cinnamon performance gains versus Mate‘s stability with each update. And new features from auto-upgrade improvements to Edge browser integration continue to divide users choosing to upgrade or lag behind the latest version.
Regardless of opinions though – quantitatively knowing the exact Mint release powering your development, testing, deployment and production systems sets the foundation. Only by confirming version specifics can you engage constructively with the community around which changes impact your use case – either in troubleshooting bugs or providing thoughtful technical feedback to distribution maintainers.
Final Thoughts – Keep Mint Fresh as a Developer
Hopefully this guide has underscored the importance of Linux Mint version checking for developers – along with techniques and best practices for validating your release. While the long-term support nature of Mint provides stability, failing to stay current with updates or being ambiguous around versions introduces risks. Know precisely what version you are running. Embrace migrations to increasingly modern bases like Ubuntu 22.04. And leverage release tracking to make informed decisions managing Linux infrastructure and application compatibility.
