1.备份镜像源
我们可以先使用下面命令查看镜像源文件
ls -l /etc/apt/sources.list.d/

然后我们需要先备份 debian.sources（主源）和 debian-backports.sources（backports 源），避免修改错误

sudo cp -a /etc/apt/sources.list.d/debian.sources /etc/apt/sources.list.d/debian.sources.bak
sudo cp /etc/apt/sources.list.d/debian-backports.sources /etc/apt/sources.list.d/debian-backports.sources.bak

2.编辑主源配置文件
直接使用下方命令编辑主源我呢见

sudo nano /etc/apt/sources.list.d/debian.sources

一开始如下图所示

直接修改其中内容，即把URIs:后面的内容全部替换成国内清华源，按照我下图方式即可

Debian archive

Types: deb
URIs: https://mirrors.tuna.tsinghua.edu.cn/debian/
Suites: trixie
Components: main contrib non-free non-free-firmware
Signed-By: /usr/share/keyrings/debian-archive-keyring.gpg

Debian stable updates

Types: deb
URIs: https://mirrors.tuna.tsinghua.edu.cn/debian/
Suites: trixie-updates
Components: main contrib non-free non-free-firmware
Signed-By: /usr/share/keyrings/debian-archive-keyring.gpg

Debian security updates

Types: deb
URIs: https://mirrors.tuna.tsinghua.edu.cn/debian-security/
Suites: trixie-security
Components: main contrib non-free non-free-firmware
Signed-By: /usr/share/keyrings/debian-archive-keyring.gpg

接下来同步更新 backports 源，也是只需要修改URIs：后面的内容，直接复制粘贴下述文本即可，可以参考图片
sudo nano /etc/apt/sources.list.d/debian.backports.sources

Debian backports

Types: deb
URIs: https://mirrors.tuna.tsinghua.edu.cn/debian/
Suites: trixie-backports
Components: main contrib non-free non-free-firmware
Enabled: yes
Signed-By: /usr/share/keyrings/debian-archive-keyring.gpg

3.更新源缓存
直接使用命令即可
sudo apt update

可以看到之前修改的清华源出现
