Report this error as below:
chroot: failed to run command ‘mount’: Exec format error
The solution is as follows：
sudo apt purge qemu-user-static
sudo apt install qemu-user-staticReference：chroot problem · Issue #5 · orangepi-xunlong/OrangePi_Build · GitHub
Fixed issue: The boot entry for /etc/rc.local file configuration does not work
Start by looking at the contents of the /etc/rc.local file to find the cause of the problem.
[root@localhost ~]# cat /etc/rc.local

According to the prompt, it may not execute because the file permissions are insufficient. So, first look at the permissions for the /etc/rc.local file.
[root@localhost ~]# ll /etc/rc.local
-rw-r--r--. 1 root root 13 Apr 21 23:06 /etc/rc.local -> rc.d/rc.local
/etc/rc.d/rc.local = /etc/rc.local = /etc/rc.local = /etc/rc.local = /etc/rc.local = /etc/rc.local = /etc/rc.local = /etc/rc.local = /etc/rc.local

-rwxr-xr-x. 1 root root 13 Apr 21 23:06 /etc/rc.d/rc.local
After restarting the server, I found that the boot items set in the /etc/rc.local file are working properly.

The situation is: CentOS 6.7 server cannot connect to the external network normally, and can only be used in the internal network. The “cannot find a valid baseurl for repo” error box pops up frequently. Here’s a screenshot:
As the system is running normally, it does not need to be updated. Therefore, by adjusting the system settings and setting the system to “never check for updates” and “never update”, this error box will not appear in the system. As shown in the figure below:

How to solve
To set the system locale, use the localectl command. For example, if you want to use UTF-8 encoded American English (US), run the following command.
download centos docker mirror system default is ISO/IEC 15897 character set

to install all of the first character set
dnf install langpacks-en glibc-all-langpacks -y
Set character set
localectl set-locale LANG=en_US.UTF-8
