Ubuntu 14.10 Utopic Unicorn Will Reach EOL Soon

Canonical has recently announced that Ubuntu 14.10 Utopic Unicorn will reach end of life (EOL) on the 23rd of July, so all the users are advised to upgrade to Ubuntu 15.04 Vivid Vervet.

While the LTS releases are supported for 5 years, a regular Ubuntu system becomes obsolete in 9 months, and after it reaches EOL, it can be still used, but the developers don’t provide security fixes anymore.

The official announcement:

“Ubuntu announced its 14.10 (Utopic Unicorn) release almost 9 months ago, on October 23, 2014. As a non-LTS release, 14.10 has a 9-month month support cycle and, as such, the support period is now nearing its end and Ubuntu 14.10 will reach end of life on Thursday, July 23rd. At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 14.10,”
