答案1

额外存储库不应有trusty-security或条目。trusty-updates

如果你去http://extras.ubuntu.com/ubuntu/dists/在您的网络浏览器中，您将看到 trusty-security 和 trusty-updates 没有列出。

运行以下命令来修复该问题：

sudo sed -i 's|deb http://extras.ubuntu.com/ubuntu trusty-security|#deb http://extras.ubuntu.com/ubuntu trusty-security|g' /etc/apt/sources.list
sudo sed -i 's|deb http://extras.ubuntu.com/ubuntu trusty-updates|#deb http://extras.ubuntu.com/ubuntu trusty-updates|g' /etc/apt/sources.list
sudo sed -i 's|deb-src http://extras.ubuntu.com/ubuntu trusty-security|#deb-src http://extras.ubuntu.com/ubuntu trusty-security|g' /etc/apt/sources.list
sudo sed -i 's|deb-src http://extras.ubuntu.com/ubuntu trusty-updates|#deb-src http://extras.ubuntu.com/ubuntu trusty-updates|g' /etc/apt/sources.list
sudo apt-get update

您应该将此错误告知“enableDisableDistribution”或向他们提交错误报告。
