默認地，我們提供了自營鏡像予Debian系統. 如果您在apt update後提示Unable to resolve的問題，請手動添加下列hosts到/etc/hosts:
10.10.10.10 debian.leikwanhost.com
該解析對於本公司所有位於上海的雲主機適用. 您亦可替換apt source為其他您中意或常用的源.
By default, we've set our own Debian source in OS template. If you get the message "Unable to resolve" after apt update, please manually add the following hosts to /etc/hosts:
10.10.10.10 debian.leikwanhost.com
This hosts is applicable for all our VMs in Shanghai, or connection can be established to Shanghai. You can also use your own Deb source.
