Are All Linux Mint Releases LTS Versions?

Not every Linux Mint version is an LTS release. The LTS version for Linux Mint is actually LMDE (Linux Mint Debian Edition). Regular Linux Mint releases are based on Ubuntu LTS versions, which come out every two years, with Mint following up a few months after. Most of the major Mint releases get five years of support, but the point releases are only supported till the major release's end of life.

Here's a helpful link: [Linux Mint All Versions](https://linuxmint.com/download_all.php). It gives you all the details on the versions and their support timelines!

You can check out the current releases and their end of life (EOL) dates at the Linux Mint download page. Basically, LM22 is supported until 2029, LM21 until 2027, while support for LM20 just ended.
