更新管理器无法更新-突触中显示 badsig 错误

可能重复：
解决 apt-get BADSIG GPG 错误的最简单方法是什么？

更新管理器声称我没有检查更新，但是我已经检查过了？

系统告诉我我没有检查更新（上次是 20 天前），但我一分钟前检查过。我正在使用 gnome shell（安装了 KDE 和 gnome），这里是 synaptic 的输出

W: GPG error: http://sd.archive.ubuntu.com oneiric Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <[email protected]>

W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://extras.ubuntu.com oneiric Release: The following signatures were invalid: BADSIG 16126D3A3E5C1192 Ubuntu Extras Archive Automatic Signing Key <[email protected]>

W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/oneiric/Release  

W: Some index files failed to download. They have been ignored, or old ones used instead.

先感谢您...

尝试这些命令...

sudo -i
apt-get clean
cd /var/lib/apt
mv lists lists.old
mkdir -p lists/partial
apt-get clean
apt-get update

这将重建缓存！
