erro de gpg de duplicidade

1

Eu tenho usado o deja dup para backup há anos agora neste mesmo computador. Recentemente, atualizei meus discos rígidos externos que uso para backup, mas comecei a fazer backups incrementais com êxito. Após cerca de um mês de backup, parece que o backup inteiro (anos de valor) está quebrado. Ele pede repetidamente senha ao tentar fazer backup ou restauração, e não chega a lugar nenhum. Aqui está a saída que recebo quando eu defino DEJA_DUP_DEBUG = 1

A minha única opção é simplesmente iniciar backups novos? Eu sinto que isso é inaceitável, pois se isso for possível novamente, não poderei restaurar nada. Eu sei que minha frase-senha está correta, já que ela nunca foi alterada e é armazenada na minha memória e no meu chaveiro (e eu a inseri manualmente muitas vezes agora sem sucesso). A solução de backup é mais confiável do que a duplicidade? Estou perdendo tempo criptografando meus backups? Obrigado pela vossa ajuda, estou bastante frustrado.

ATUALIZAÇÃO: acabou de iniciar um novo backup do zero. Oh bem.
