從 12.10 升級到 14.10 時出現此錯誤：

W:Failed to fetch http://security.ubuntu.com/ubuntu/dists/raring-security/main/source/Sources  404  Not Found [IP: 91.189.91.15 80]

我該怎麼辦？

測試一下：

打開終端，

按Ctrl+ Alt+T

運行：

sudo -i
nano /etc/apt/sources.list

在打開的文件中。

刪除內容。

貼上以下內容：

ADDKERNEL="linux-(image|headers|ubuntu-modules|restricted-modules)"
METAKERNEL="linux-(image|headers|restricted-modules)-(generic|i386|server|common|rt|xen)"
UNUSKERNELS=$(dpkg -l|awk '{print $2}'|grep -E $ADDKERNEL |grep -vE $METAKERNEL|grep -v $NEWKERNEL)
apt-get remove --purge $UNUSKERNELS
apt-get update
apt-get dist-upgrade
dpkg --configure -a
