早上好，Ping-Wu先生。

Debian Testing “Bullseye”: The Repository Does Not Have a Release File

Unfortunately, the Debian maintainers managed to let a bug creep into the /etc/apt/sources.list. It’s called "Testing" for a reason, I guess.
不幸的是，Debian维护人员设法让一个bug潜入/etc/apt/sources.list。我想这叫做“测试”是有原因的。
The offending lines are this.
冒犯的台词是这样的。

より良い文証を発見。

Debian 11 Bullseye で セキュリティ更新の命名法に変更がありました。

第 6 章 メンテナンスと更新、APT ツール - 6.1.3. テスト版/不安定版ユーザ向けリポジトリ
https://www.debian.org/doc/manuals/debi ... st.testing

NOTE Layout of security repositories

Starting with Debian 11 Bullseye, the codename of the repository providing security updates has been renamed from codename/updates into codename-security to avoid the confusion with codename-updates (see 第 6.1.2.2 節「安定版更新」).

codename-updates との混同を避けるために、codename/updates から codename-security に変更。
为了避免与codename-updates混淆，从codename/updates变更为codename-security。

Debian 11 官方版的 /etc/apt/source.list 有误 (エラー) ，以致无法进行 sudo apt update，必须修改 (正しい ) 。我们建议桌面系统使用者顺便加入 contrib 及 non-free 套件库。

For desktop systems, it is recommended to correct (正しい エラー) the original /etc/apt/source.list file (in red color 赤 ) and add (in blue color 青) contrib and non-free repositories:

deb http://deb.debian.org/debian bullseye main contrib non-free
deb-src http://deb.debian.org/debian bullseye main contrib non-free

deb http://deb.debian.org/debian bullseye-updates main contrib non-free
deb-src http://deb.debian.org/debian bullseye-updates main contrib non-free

deb http://security.debian.org/debian-security/ bullseye-updates bullseye-security main contrib non-free
deb-src http://security.debian.org/debian-security/ bullseye-updates bullseye-security main contrib non-free

[Ping-Wu]

初次使用 Debian 11 桌面的 Linux 老手，建议使用下列档案取代官方版的 /etc/apt/source.list:

代码： 全选

deb http://deb.debian.org/debian bullseye main contrib non-free
deb-src http://deb.debian.org/debian bullseye main contrib non-free

deb http://deb.debian.org/debian bullseye-updates main contrib non-free
deb-src http://deb.debian.org/debian bullseye-updates main contrib non-free

deb http://security.debian.org/debian-security/ bullseye-security main contrib non-free
deb-src http://security.debian.org/debian-security/ bullseye-security main contrib non-free
