You are attempting to upgrade to a version of Trisquel that is no longer supported. Since we do only keep upgrade packages for decomissioned releases for a while, this upgrade may fail. Try the sandbox method first (by running update-manager -s) or ask in our forums, lists or irc channels if you are unsure about this procedure.
Even if the required upgrade packages for nabia are still available, to get a currently supported release you would need to upgrade at least once more after this procedure ends, so we recommend you to do a clean install using the latest LTS or STS edition.
