ubuntu使用时发现
每次update都出现问题
E: Release file for http://ports.ubuntu.com/dists/bionic-backports/InRelease is not valid yet (invalid for another 14d 17h 36min 13s). Updates for this repository will not be applied.

其实是时间设置不同步导致：
需要从新设置时间
- 输入以下
root@ubuntu:/# tzselect
- 后选择亚洲-中国-北京（输入前面的标号后回车即可）
- 复制文件到/etc目录下
root@ubuntu:/# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
- 再次查看时间date -R，已经修改为北京时间
- 修改时间
sudo date -s MM/DD/YY //修改日期
sudo date -s hh:mm:ss //修改时间
- 在修改时间以后，修改硬件CMOS的时间
- 非常重要，如果没有这一步的话，后面时间还是不准
sudo hwclock --systohc
以上结束。
