Linux Mint 6 Felicia will reach end of life on April 30, 2010. This release was based on Ubuntu 8.10 which is planned to reach end-of-life at the same date.
Repositories will remain open for another while but no more updates or security fixes will be made available. Users of Linux Mint 6 Felicia are asked to migrate to Linux Mint 8 Helena (which will be supported until April 2011) or to wait for the upcoming Linux Mint 9 LTS Isadora (Long Term Release which will be released in the end of May and supported until April 2013).
Announcement from Ubuntu: “As with the earlier releases, Ubuntu committed to ongoing security and critical fixes for a period of 18 months. The support period is now nearing its end and Ubuntu 8.10 will reach end of life on Friday, April 30, 2010. At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 8.10.”
Note: Linux Mint follows the Ubuntu release cycle with a new release every 6 months, a lifespan of about 1.5 years per release and 3 years per LTS release. LTS stands for Long Term Support. Linux Mint 9 will be an LTS release.
