/etc/apt/sources.list	Set the source of the software package
/etc/apt/apt.conf	apt configuration file
/etc/apt/apt.conf.d/	apt's fragmented configuration file
/etc/apt/preferences	Version parameters
/var/cache/apt/archives/	Store the downloaded software package
/var/cache/apt/archives/partial	Store the software package being downloaded
/var/lib/apt/lists/	Store the downloaded software package details
/var/lib/apt/lists/partial/	Store the details of the software package being downloaded

Update the apt in the container and replace the source domain name in /etc/apt/sources.list with mirrors.aliyun.com

mirrors.aliyun.com
