重新安装了armdian系统，更新软件源得时候GPT报错，更新GPT的时候又发现系统时间不对，GPT安装不上。记录一下是怎么解决的。

{mtitle title=GPT报错/}

更新ＧＰＴ

apt-key adv --keyserver keyserver.ubuntu.com --recv 密钥

密钥在报错的信息里边，如图上就是 0E98404D386FA1D9 、 648ACFD622F3D138 、 0E98404D386FA1D9 这几个密钥报错，执行 apt-key adv --keyserver keyserver.ubuntu.com --recv 648ACFD622F3D138 命令即可解决，一个密钥一条命令。

修改系统时间

执行命令

tzselect

在出现的结果中，用数字选择大洲、国家、地区

root@Chainedbox:~# tzselect

Please select one of the following timezones.
1) Beijing Time
2) Xinjiang Time
#? 1

The following information has been given:

        China
        Beijing Time

Therefore TZ='Asia/Shanghai' will be used.
Selected time is now:   Sun Oct 24 11:11:56 CST 2021.
Universal Time is now:  Sun Oct 24 03:11:56 UTC 2021.
Is the above information OK?
1) Yes
2) No
#? 1

You can make this change permanent for yourself by appending the line
        TZ='Asia/Shanghai'; export TZ
to the file '.profile' in your home directory; then log out and log in again.

Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
Asia/Shanghai
root@Chainedbox:~#

将修改结果存入本地文件中

cp /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime

更新系统时间

ntpd time.windows.com

验证是否修改成功

date -R

可以看到修改完成，此时将系统重启，以免计划任务执行异常

root@Chainedbox:~# date -R
