一、前言

我找到了很多方法，比如修改阿里云镜像，清华大学镜像，然后执行 sudo apt-get update等等，总是失败。

root@sonic:/etc/apt# sudo apt-get update  Get:1 http://debian-archive.trafficmanager.net/debian bullseye InRelease [116 kB]        Get:2 http://debian-archive.trafficmanager.net/debian-security bullseye-security InRelease [44.1 kB] Get:3 http://debian-archive.trafficmanager.net/debian bullseye-backports InRelease [44.2 kB] Get:4 https://download.docker.com/linux/debian bullseye InRelease [43.3 kB]              Reading package lists... Done                                                                                                                                                E: Release file for http://debian-archive.trafficmanager.net/debian/dists/bullseye/InRelease is not valid yet (invalid for another 97d 16h 31min 18s).

后来偶然看到这边的博文 链接地址的原 ，确定是系统时间戳不正确造成的问题。

二、修改时区和更新时间

1、概念

查看当前时间

root@sonic:/etc/apt# date -R # 查看系统时间 Sat, 02 Apr 2022 17:18:04  0000  # 当前时区为0时区 root@sonic:/etc/apt#  root@sonic:/etc/apt# sudo hwclock --show # 检查硬件时间 2022-04-02 17:18:15.655539 00:00 

3、运行 tzselect 选择时区

4.复制文件到 /etc 并在目录下查看时区

root@sonic:/etc/apt# sudo cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime root@sonic:/etc/apt# date -R Sun, 03 Apr 2022 01:20:59  0800  # 时区为东8区 root@sonic:/etc/apt#  

5.设置正确的系统时间

roo@sonic:/etc/apt# sudo date -s 07/12/22 # 修改日期
Tue 12 Jul 2022 12:00:00 AM CST
root@sonic:/etc/apt# sudo date -s 15:38:00 # 修改时间
Tue 12 Jul 2022 03:38:00 PM CST
root@sonic:/etc/apt# sudo hwclock --systohc # 修改硬件CMOS时间；这个步骤非常重要,如果没有这一步,重启后,时区又会发生改变
root@sonic:/etc/apt# 
root@sonic:/etc/apt# 
root@sonic:/etc/apt# date
Tue 12 Jul 2022 03:38:16 PM CST  # 系统时间正确
root@sonic:/etc/apt#
