Dear Tiago,
trying to install graph-tool on a ubuntu machine, I got the following error:
W: GPG error: https://downloads.skewed.de/apt bionic InRelease: The following signatures were invalid: EXPKEYSIG 7A80C8ED4FCCBE09 Tiago de Paula Peixoto <tiago@skewed.de> E: The repository 'https://downloads.skewed.de/apt bionic InRelease' is not signed.
I suppose this relates to the PGP key at the end of https://downloads.skewed.de/apt/dists/bionic/InRelease <https://downloads.skewed.de/apt/dists/bionic/InRelease>.
Could you let me know if the key is indeed expired or if it is an issue on my side?
Just try downloading the key again from the keyserver, and you should get an updated one. Best, Tiago -- Tiago de Paula Peixoto <tiago@skewed.de>
