更換 apt-get 來源

Posted on 2014 年 10 月 23 日 by cowman.chiang

root@ubuntu:~# vim /etc/apt/sources.list :%s/us.archive.ubuntu.com/tw.archive.ubuntu.com/g 或是 root@ubuntu:~# sed -i ‘s/us.archive.ubuntu.com/tw.archive.ubuntu.com/g’ /etc/sources.list 記得要在apt-get update一下.. 基本上國網 free.nchc.org 應該也可以 但是不知道為什麼一直出錯 如果想要用國網的點，就把tw.archive.ubuntu.com改成free.nchc.org
