Released on May 31st, 2014, the Linux Mint 17 operating system series was an LTS (Long Term Support) version that received security patches and software updates for five long years. It comprised of a total of four releases, including Linux Mint 17 “Qiana”, Linux Mint 17.1 “Rebecca”, Linux Mint 17.2 “Rafaela”, and Linux Mint 17.3 “Rosa”. The Linux Mint 17 series was based on the Ubuntu 14.04 LTS (Trusty Tahr) operating system series, which recently reached end of life. While Canonical is continuing to support Ubuntu 14.04 installations through its commercial ESM (Extended Security Maintenance) offering, Linux Mint 17 will no longer be supported with security or software updates.
