22.04로 업데이트해 볼 텐데, 생각했던 것보다 간단했습니다. ^^
Upgrading Ubuntu 20.04 to 22.04 LTS using the command line
; https://krystal.io/blog/post/upgrading-ubuntu-20-04-to-22-04-lts-using-the-command-line
위의 글을 참고해, 우선 20GB 정도 여유 공간 있는 거 확인하고,
$ df -h
Filesystem Size Used Avail Use% Mounted on
udev 3.9G 0 3.9G 0% /dev
tmpfs 794M 1.5M 793M 1% /run
/dev/sda2 47G 23G 22G 51% /
...[생략]...
/dev/loop3 313M 313M 0 100% /snap/code/160
패키지 업데이트, 재부팅 및 방화벽 열어주고,
$ sudo apt update && sudo apt upgrade -y
$ sudo reboot
$ sudo ufw allow 1022/tcp
업데이트를 시작하는데 원문에서는 (그 당시의 상황에서는 맞았을) "-d"를 붙이라고 했지만,
$ sudo do-release-upgrade -d
Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS development release
set Prompt=normal in /etc/update-manager/release-upgrades.
"-d"는 "development release"를 의미한다고 합니다.
$ cat /etc/update-manager/release-upgrades
# Default behavior for the release upgrader.
[DEFAULT]
# Default prompting and upgrade 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
현재(2024-06-11)는 22.04 LTS 버전까지 나와 있는 상태이므로 "-d"를 빼고 업데이트를 시작합니다.

시간만 좀 걸렸을 뿐 마음에 드는 업데이트 경험이었습니다. ^^
참고로, 현재 최신 LTS 버전은 24.04 버전인데 이에 대한 (22.04로부터의) 자동 업데이트는 24.04.1 버전이 나올 8월 15일 즈음이라고 합니다.
