Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS develoment release
set Prompt=normal in /etc/update-manager/release-upgrades.`
¿Por qué mi administrador de actualizaciones dice que no hay una versión de "desarrollo" de un LTS disponible?
17:41UTC:root@bard:~# cat /etc/update-manager/release-upgrades
# Default behavior for the release upgrader.
[DEFAULT]
# Default prompting behavior, valid options:
#
# never - Never check for, or allow upgrading to, a new release.
# normal - Check to see if a new release is available. If more than one new
# release is found, the release upgrader will attempt to upgrade to
# the supported release that immediately succeeds the
# currently-running release.
# lts - Check to see if a new LTS release is available. The upgrader
# will attempt to upgrade to the first LTS release available after
# the currently-running one. Note that if this option is used and
# the currently-running release is not itself an LTS release the
# upgrader will assume prompt was meant to be normal.
Prompt=lts
Este sistema tiene [lo que me parece] un /etc/apt/sources.listarchivo genérico. Apunta a varios ubuntu.comrepositorios Bionic.

¡Vaya! Situación especial: errores críticos por los cuales Canonical está reteniendo Focal. La versión "puntual" (20.04.01) ya está disponible, pero aún no está "lanzada" para las actualizaciones desde 18.04LTS
