Canonical publicó ayer la más reciente versión de Ubuntu, una de las distribuciones gratis de Linux para PC más populares (según la compañía está en 25 millones de equipos).
Es la 15.04 Vivid Vervet (el nombre ordinal alude al mono cercopiteco verde).
E incluye cambios que no serán particularmente visibles para el usuario convencional, como el uso Unity 7.3, el entorno de escritorio que usa Ubuntu, y que en este caso recibe múltiples arreglos de errores menores, además de la posibilidad de hacer que los menús se vean en forma permanente, y de la incorporación de Systemd en vez de Upstart para cargar módulos durante el arranque.
En lo que refiere a Kubuntu, usará Plasma 5.2 (el escritorio de KDE); Xubuntu hace lo propio con Xfce 4.12. Como novedad, la versión 15.04 es la primera que tiene a Ubuntu MATE (la distribución que usa un entorno de escritorio con un concepto más tradicional, y que nació de la mano de un argentino) como versión oficial de la familia Ubuntu. Entre sus novedades está el soporte para correr en una Raspberry Pi 2.
Ubuntu (como la enorme mayoría de las distribuciones de Linux) se puede grabar en un DVD o en un pendrive, correr desde cualquiera de los y probar en una PC sin modificar Windows, o instalarlo junto a él (o como reemplazo) si el usuario así lo desea.
Canonical has announced the launch of Ubuntu 15.04. The new release, which will be supported for nine months, features LibreOffice 4.4, version 3.19 of the Linux kernel and a switch from Canonical's Upstart init to systemd. "systemd has replaced Upstart as the standard boot and service manager on all Ubuntu flavors except Touch. At the time of the 15.04 release there are no known major problems which prevent booting. The only service which does not currently start is Juju, which will be fixed in a post-release update soon; all other packaged Ubuntu services are expected to work. Upstart continues to control user sessions... You can boot with Upstart once by selecting `Advanced options for Ubuntu' in the GRUB boot menu and starting the `Ubuntu, with Linux ... (upstart)' entry. To switch back permanently, install the upstart-sysv package (this will remove systemd-sysv and ubuntu-standard)." The new release offers several updates and improvements for LXC containers and this is the first version of Ubuntu to offer the LXD container management utility. Ubuntu is available in a number of editions, including Desktop, Server and Snappy, a minimal "core" installation. More details on Ubuntu 15.04 can be found in the release notes.
