Aramo Key Transition
Including the Aramo key in the trisquel-keyring for nabia-updates is helpful for people that already have Trisquel installed, as it ensures that the key's signed by the prior one and creating a chain for however long their installation's been around.
If someone's just starting with Trisquel, though, they don't get this benefit. May I recommend doing what Debian does?

They have the new key sign the old one, and it's also signed by the Debian FTP masters.
In concrete terms that would mean using the old archive signing key to sign the new one, and also signing the new key by perhaps e.g. quidam, and then sending those signatures to a GPG key server.
In terms of new users, that could allow a web of trust to determine how much to trust the keys, based on who has signed the key.
