Ubuntu 24.04 LTS 后的source.list

24.04LTS 后，apt源的位置替换到了/etc/apt/sources.list.d/ubuntu.sources中

/etc/apt/sources.list# Ubuntu sources have moved to the /etc/apt/sources.list.d/ubuntu.sources# file, which uses the deb822 format. Use deb822-formatted .sources files# to manage package sources in the /etc/apt/sources.list.d/ directory.# See the sources.list(5) manual page for details.

同时，格式改变，现在为DEB822格式，详见这里

现在的格式是这样的

/etc/apt/sources.list.d/ubuntu.sources## /etc/cloud/templates/sources.list.ubuntu.deb822.tmpl### See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to# newer versions of the distribution.## Ubuntu distribution repository#### The following settings can be adjusted to configure which packages to use from Ubuntu.## Mirror your choices (except for URIs and Suites) in the security section below to## ensure timely security updates.#### Types: Append deb-src to enable the fetching of source package.## URIs: A URL to the repository (you may add multiple URLs)## Suites: The following additional suites can be configured## <name>-updates - Major bug fix updates produced after the final release of the## distribution.## <name>-backports - software from this repository may not have been tested as## extensively as that contained in the main release, although it includes## newer versions of some applications which may provide useful features.## Also, please note that software in backports WILL NOT receive any review## or updates from the Ubuntu security team.## Components: Aside from main, the following components can be added to the list## restricted - Software that may not be under a free license, or protected by patents.## universe - Community maintained packages.## Software from this repository is only maintained and supported by Canonical## for machines with Ubuntu Pro subscriptions.

因此，如果要使用国内诸如清华TUNA源，USTC源，也需要使用新格式

具体方法

sources.list.d文件夹中，所有.sources拓展名结尾的文件均会被作为一个可选的源

因此我们将原始文件备份：

sudo mv /etc/apt/sources.list.d/ubuntu.sources /etc/apt/backup-sources.list.d-ubuntu.sources

然后创建一个新的文件，以.sources结尾，例如

sudo vim /etc/apt/sources.list.d/tuna.sources

里面填入

Types: debURIs: https://mirrors.tuna.tsinghua.edu.cn/ubuntu/#如果使用其他镜像站，上面这行可以改成其他镜像站的网址Suites: noble noble-updates noble-backportsComponents: main universe restricted multiverseSigned-By: /usr/share/keyrings/ubuntu-archive-keyring.gpgTypes: debURIs: http://security.ubuntu.com/ubuntu#如果安全更新需要使用镜像站，上面这行也改成 URIs: https://mirrors.tuna.tsinghua.edu.cn/ubuntu/Suites: noble-securityComponents: main universe restricted multiverseSigned-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

之后运行

$ sudo apt update$ sudo apt upgrade
