Hi, all friends!
   I want to install graph_tool in Ubuntu 12.04.
   I add the source to my sources.list and update the source.
   It replys "W: GPG error: http://downloads.skewed.de oneiric Release: The following signatures couldn't be verified because the         public key is not available: NO_PUBKEY 697EC21F15F95514"
   I don't know how to add the public key.
   I tried to save F36FE35D in keyfile and "sudo apt-key add keyfile" .
   But it says"gpg: no valid OpenPGP data found."
   What is this problem? Thank you for your suggestion.

Hi,

I've released a new version of graph-tool (2.2.17). Could you please try again
with apt-get?

I tried it on an ubuntu machine, and everything worked nicely...

Cheers,
Tiago
