　　解决方案，CA证书 apt-get install --reinstall ca-certificates
　　然后重新运行 apt-get update：root@DESKTOP-R5MSHA1:~# apt-get update Hit:1 https://mirrors.aliyun.com/debian bullseye InRelease Get:2 https://mirrors.aliyun.com/debian-security bullseye-security InRelease [48.4 kB] Hit:3 https://mirrors.aliyun.com/debian bullseye-updates InRelease Get:4 https://mirrors.aliyun.com/debian bullseye-backports InRelease [49.0 kB] Get:5 https://mirrors.aliyun.com/debian bullseye/contrib Sources [43.2 kB] Get:6 https://mirrors.aliyun.com/debian bullseye/non-free Sources [81.2 kB] Get:7 https://mirrors.aliyun.com/debian bullseye/main Sources [8,633 kB] Get:8 https://mirrors.aliyun.com/debian bullseye/non-free amd64 Packages [97.7 kB] Get:9 https://mirrors.aliyun.com/debian bullseye/non-free Translation-en [92.4 kB] Get:10 https://mirrors.aliyun.com/debian bullseye/contrib amd64 Packages [50.6 kB] Get:11 https://mirrors.aliyun.com/debian bullseye/contrib Translation-en [46.9 kB] Get:12 https://mirrors.aliyun.com/debian-security bullseye-security/main Sources [169 kB] Get:13 https://mirrors.aliyun.com/debian-security bullseye-security/main amd64 Packages [200 kB] Get:14 https://mirrors.aliyun.com/debian-security bullseye-security/main Translation-en [129 kB] Get:15 https://mirrors.aliyun.com/debian bullseye-updates/main Sources [4,812 B] Get:16 https://mirrors.aliyun.com/debian bullseye-backports/main Sources [358 kB] Get:17 https://mirrors.aliyun.com/debian bullseye-backports/contrib Sources [2,868 B] Get:18 https://mirrors.aliyun.com/debian bullseye-backports/non-free Sources [4,552 B] Get:19 https://mirrors.aliyun.com/debian bullseye-backports/main amd64 Packages [361 kB] Get:20 https://mirrors.aliyun.com/debian bullseye-backports/main Translation-en [297 kB] Get:21 https://mirrors.aliyun.com/debian bullseye-backports/non-free amd64 Packages [14.3 kB] Get:22 https://mirrors.aliyun.com/debian bullseye-backports/non-free Translation-en [26.6 kB] Get:23 https://mirrors.aliyun.com/debian bullseye-backports/contrib amd64 Packages [4,400 B] Get:24 https://mirrors.aliyun.com/debian bullseye-backports/contrib Translation-en [4,320 B] Fetched 10.7 MB in 2min 3s (86.9 kB/s) Reading package lists...
