The following is a short reminder for those of you who still use the Ubuntu 13.04 operating system that Canonical will no longer provide security/critical fixes and software updates for the Raring Ringtail distribution.
As we reported at the beginning of the month, the Ubuntu 13.04 (Raring Ringtail) Linux operating system was supposed to reach end of life (EOL) today, January 27, 2014.
Therefore, Canonical ended the support period for Ubuntu 13.04 and urges users to upgrade to a newer version as soon as possible. Detailed instructions and caveats for the entire upgrade process can be found at https://help.ubuntu.com/community/SaucyUpgrades.
Officially announced 9 months ago, on Thursday, April 25, 2013, Ubuntu 13.04 (Raring Ringtail) was the first of its kind to introduce two new flavors, the Ubuntu GNOME and Ubuntu Kylin operating systems.
