?不同的網(wǎng)絡(luò)狀況連接以下源的速度不同, 建議在添加前手動驗(yàn)證以下源的連接速度(ping下就行),選擇最快的源可以節(jié)省大批下載時間。

• 首先備份源列表(for sure):

sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

• 而后用gedit或其他編輯器打開:

gksu gedit /etc/apt/sources.list kdesudo kate /etc/apt/sources.list gksu mousepad /etc/apt/sources.list gksu leafpad /etc/apt/sources.list (12.04版) gksu gedit /etc/apt/sources.list

• 從下面列表中選擇合適的源，替換掉文件中所有的內(nèi)容，保存編輯好的文件:

?注意：一定要選對版本

• 然后，刷新列表:

sudo apt-get update

?注意：一定要執(zhí)行刷新
