gpg --keyserver keyserver.ubuntu.com --recv-key E084DAB9
gpg: requesting key E084DAB9 from hkp server keyserver.ubuntu.com
gpgkeys: HTTP fetch error 7: couldn't connect to host
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

I had some problems with this just a few days ago.
You need to import that GPG key. See the section "secure APT" here:
