Após algumas tentativas e erros, descobri que a única solução seria desinstalar todos os pacotes relacionados a maas dpkg -r e reinstalar o maas a partir do zero.
Eu tentei atualizar minha instalação do MAAS como ela foi descrita aqui: Atualizando o MAAS de 1.5.4 para 1.7.0 ou mais recente no Ubuntu 14.04 mas há um erro em um dos scripts python usados durante o atualizar. Eu recebo a seguinte saída:

Depois disso, a instalação apenas espera lá e eu tenho que parar com força o apt-get. Chamar apt-get upgrade repete isso. Eu também não consigo remover o pacote maas-region-controller porque isso resulta em
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
que novamente aciona a instalação com o erro.
Existe uma maneira de reparar esta instalação?
