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 que meu gerenciador de atualização diz que não há versão de “desenvolvimento” de um LTS disponível?
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 tem [o que me parece] um /etc/apt/sources.listarquivo genérico. Aponta para vários ubuntu.comrepositórios Bionic.

oh! situação especial: bugs críticos para os quais a Canonical está retendo o Focal. A versão "pontual" (20.04.01) foi lançada, mas ainda não foi "lançada" para atualizações de 18.04LTS
