我在四月份升级到了 24.04 开发分支。从那时起,我就一直保持系统更新。今天,在“设置”中,它显示我有“Ubuntu Noble Numbat(开发分支)”。
我该怎么做才能不进入“开发分支”?我的印象是,我只需要继续使用 apt 进行升级即可实现这一点。
我尝试过do-release-upgrade
、、apt full-upgrade
重启两次。没有发现任何变化。
更新
lsb_release -a
:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu Noble Numbat (development branch)
Release: 24.04
Codename: noble
这看起来不对。
输出apt update

缺少签名——是这个原因吗?
/etc/apt/sources.list 的内容:
# Ubuntu sources have moved to /etc/apt/sources.list.d/ubuntu.sources
/etc/apt/sources.list.d/ubuntu.sources 的内容:

新的来源格式看起来更容易阅读,但我不确定那里应该有什么。
