[Qgis-user] GPG Keyerror

[Spencer Gardner]

I've started getting a GPG Keyerror when upgrading QGIS nightly builds on my Ubuntu machine. It says something about an expired GPG key (I'm not at home so I can't remember the exact error message). Is this a known issue that needs to be fixed in the repository, or is there something that I need to change on my machine? 

I tried removing the old key and re-downloading but it's still giving me the same error.

Thanks!
