XuWentao failed to run scrarchbox installation script, because he do not know how to set proxy for wget i solved this problem this way $vim ~/.wgetrc export PROXY=http://211.90.168.94:8080/ export http_proxy = http://211.90.168.94:8080/ export ftp_proxy = http://211.90.168.94:8080/ and then source ./wgetrc but even now wget http://www.baidu.com can not be done you have to use wget -Y on -p -k https://www.baidu.com/ so i think i can replace all the "wget" in the script with "wget -Y on -p -k" but when i open the script i find out that wget is not in use run the script now, it is now able to connect to the outside web, great!
