2. Restore the Trusted Debian Mirror

Edit your sources:

bash
sudo nano /etc/apt/sources.list

Replace all https://mirrors.tuna.tsinghua.edu.cn with:

bash
deb http://deb.debian.org/debian bookworm main contrib non-free deb http://security.debian.org/debian-security bookworm-security main contrib non-free deb http://deb.debian.org/debian bookworm-updates main contrib non-free

Save and exit.

✅ 3. Fix Missing Certificates

You're missing the ca-certificates package, so HTTPS fails. Fix it manually:

    1. Get the .deb from a working system or from a browser:

      URL:
      https://deb.debian.org/debian/pool/main/c/ca-certificates/ca-certificates_20230311_all.deb

    2. Transfer it to your broken system, then install:

      bash
      sudo dpkg -i ca-certificates_20230311_all.deb sudo update-ca-certificates

 

 

然后再换回清华的源，问题就解决了。
