由于 GPG 错误，apt-get 更新在 Ubuntu 14.04 中失败

我目前使用的是 Ubuntu 14.04（Ubuntu 新手，最近迁移）。

“apt-get install” 运行正常，我的连接也运行正常。但是当我运行 apt-get update 时，发生了以下情况

100% [InRelease gpgv 3,627 B] [Connecting to security.ubuntu.com  
(91.189.91.13)Splitting up /var/lib/apt/lists/partial
/in.archive.ubuntu.com_ubuntu_dists_trustyIgn 
http://in.archive.ubuntu.com trusty InRelease                              

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

在网上进行了详尽的搜索，但没有找到任何明确的解决方案。到目前为止，我尝试过的方法：

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

对于懒人来说，fixpackage 中包含的内容如下：

sudo cp -arf /var/lib/dpkg /var/lib/dpkg.backup
sudo cp /var/lib/dpkg/status-old /var/lib/dpkg/status
sudo cp /var/lib/dpkg/available-old /var/lib/dpkg/available
sudo rm -rf /var/lib/dpkg/updates/*
sudo rm -rf /var/lib/apt/lists
sudo mkdir /var/lib/apt/lists
sudo mkdir /var/lib/apt/lists/partial
sudo apt-get clean
sudo apt-get update
sudo dpkg --clear-avail
sudo dpkg --configure -a
sudo apt-get install -f
sudo apt-get update
sudo apt-get dist-upgrade

输出：

我也尝试过这个解决方案

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

这两种解决方案对我来说都不起作用。

如果需要更多详细信息，请告诉我。

答案1

我遇到了同样的问题，因为我在公司使用代理。解决方案是

  1. 您需要设置环境变量

http_proxy

  1. 使用 sudo 命令并加上选项

-E

sudo -E apt-get 更新

该选项指示 sudo 命令执行保存环境变量。
