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

先感谢您...
