Itanium
and Debian no longer supports Itanium officially (last release with official support was Debian 7 / Wheezy, and was not covered by Long Term Support (LTS), but unofficial support for newer Debian is still available in limited form via Debian Ports; last available kernel in wheezy-backports is Linux 3.14.0, which was released on March 30, 2014, but it is possible to manually update to latest 3.14.x version, or more recent kernel versions, like 4.17.17 as of September 2018) and in addition Canonical Ltd. chose to not support Itanium for Ubuntu 10.04 LTS (released in April 2010, now discontinued).
