[Ubuntu] Ubuntu24.04 升级撤包了？

前几天推出 24.04.1 之后就开始推送升级了，天天弹出提示，昨天 do-release-upgrade 决定升级，能检测到更新，结果磁盘空间不足。今天整理好硬盘空间足够了以后，刚刚想升级，跑了下 do-release-upgrade

$ sudo do-release-upgrade
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.


这是撤包了嘛？
