openSUSE — bash
$ gpg --keyserver hkps://keys.openpgp.org --recv-keys 78BD65473CB3BD13

Additional notes

Google rotates its Linux repo signing key periodically. If this fix stops working, check the official page for the current key fingerprint.

After importing the key

Run sudo apt-get update (or your distro's equivalent) again. If successful you should see Hit: lines with no EXPKEYSIG warnings. Still broken? Check that your /etc/apt/sources.list.d/ entry references the correct [signed-by=…] keyring path.
