Dav*_*ths 5 updates duplicate-files 12.04
我在终端中运行 sudo apt-get update 时收到此消息：- Duplicate sources.list entry http://archive.canonical.com/ubuntu/precision/partner i386 Packages (/var/lib/apt/lists/archive .canonical.com_ubuntu_dists_precise_partner_binary-i386_Packages）
所以我运行了命令 gksu gedit /etc/apt/sources.list 并检查了源代码以发现没有重复项，无论如何我都看不到。这是来源：-

我对 linux 操作系统很陌生，几乎没有来源编辑技能，因此非常感谢任何帮助。
谢谢：）
