My name is Ori and I'd like to join your community but it is hard to do so without being able to install neo4j on my machine. I'm using ubuntu 18.04 (LTS), and after following the installation instructions, I ran into a GPG invalid signature. The relevant error seems to be:
W: GPG error: http://debian.neo4j.org/repo stable/ Release: The following signatures were invalid: EXPKEYSIG 26C95CF201182252 Neo Technology Admins <firstname.lastname@example.org>
E: The repository 'http://debian.neo4j.org/repo stable/ Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
I can't paste the whole session because I'm limited to 5 links in this post. Thanks for your help!
