Answer 1

当我运行sudo apt-get update 时出现错误：

Ign http://br.archive.ubuntu.com trusty InRelease                              
E: GPG error: http://br.archive.ubuntu.com trusty InRelease: Clearsigned file isn't valid, got 'NODATA' (does the network require authentication?)

为了解决这个问题，首先我尝试了：

wget https://dl.dropbox.com/u/8850924/fixpackage
chmod +x ./fixpackage
sudo ./fixpackage

正如https://answers.launchpad.net/ubuntu/+question/251767 中推荐的那样

但它对我不起作用。所以最后我尝试了以下几行，它解决了我的问题：

sudo apt-get clean
sudo mv /var/lib/apt/lists /var/lib/apt/lists.broke
sudo mkdir -p /var/lib/apt/lists/partial
sudo apt-get update
