Não é possível atualizar automaticamente o Tails

Inicializei o Tails 2.4 e fui recebido com:

Erro ao verificar atualizações

Executar a atualização manualmente no terminal revela erros:

amnesia@amnesia:~$ tails-upgrade-frontend-wrapper

Como atualizar sem reinstalação manual completa?

O problema está nos certificados:

Could not download 'https://tails.boum.org/upgrade/v1/Tails/2.4/i386/stable/upgrades.yml',
request failed (Peer certificate cannot be authenticated with given CA certificates):
server certificate verification failed. CAfile: /usr/local/etc/ssl/certs/tails.boum.org-CA.pem

https://tails.boum.orgmudou para a autoridade de certificação Let's Encrypt e esses novos certificados estão faltando em versões anteriores2.7.

Você pode consertar isso baixando Lets encrypt certs:

  1. Vá parahttps://letsencrypt.org/certificates/
  2. abra um dosAtivoCertificados Intermediários ->Vamos criptografar a autoridade X3 (assinatura cruzada IdenTrust)
  3. abra tails.boum.org-CA.peme substitua seu conteúdo pelo certificado Let's encrypt.

sudo nano /usr/local/etc/ssl/certs/tails.boum.org-CA.pem (Você precisará configurar a senha de administração antes)

Em seguida, execute novamente tails-upgrade-frontend-wrapper.

Repita até que o Tails 2.7 esteja instalado.

Quando você (ou outra pessoa) tem um Tails mais recente, você pode atualizar seu stick a partir do Tails em execução mais recente. Basta usar o instalador do Tails. Ele não baixa os tails da rede, mas usa os tails em execução.

Dica: Conecte o tails mais antigo somente após o instalador do Tails ter sido iniciado.
