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.`
내 업그레이드 관리자가 사용 가능한 LTS의 "개발" 버전이 없다고 말하는 이유는 무엇입니까?
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

오! 특수 상황: Canonical이 Focal을 방해하는 심각한 버그. "포인트" 릴리스(20.04.01)가 출시되었지만 18.04LTS의 업그레이드를 위해 아직 "릴리스"되지 않았습니다.
