问apt update 升级debian jessie KEYEXPIRED 1587841717?

解决方法

1、查看过期信息

root@debian:/opt# apt-key list | grep expired -A1

pub 4096R/46925553 2012-04-27 [expired: 2020-04-25]

uid Debian Archive Automatic Signing Key (7.0/wheezy) <ftpmaster@debian.org>

pub 4096R/65FFB764 2012-05-08 [expired: 2019-05-07]

uid Wheezy Stable Release Key <debian-release@lists.debian.org>

2、修改系统时间，时间小于上面最小过期时间2019-05-07即可

date -s "20180101 18:30:00"

3、root@debian:/opt# apt-get update --allow-unauthenticated

Ign http://mirrors.163.com jessie InRelease

Get:1 http://mirrors.163.com jessie Release.gpg [2,420 B]

Hit http://mirrors.163.com jessie Release

...

Fetched 2,420 B in 11s (217 B/s)

成功

4、修改回系统时间即可

网上提到的方法试过了，无效

1、修改源为网易 /etc/apt/sources.list

deb [trusted=yes] http://mirrors.163.com/debian-archive/debian/ jessie main non-free contrib

2、设置 /etc/apt/apt.conf

APT::Install-Recommends "false";

Get::AllowUnauthenticated true;

Acquire::Check-Valid-Until false;

3、更新 apt update仍然出现
