Debian - “AVISO: versões não confiáveis dos seguintes pacotes serão instaladas!”

Question

Quando tento instalar ou atualizar quaisquer pacotes que recebo:

Untrusted packages could compromise your system's security. You should only proceed with the installation if you are certain that this is what you want to do.

Suspeito que isso esteja relacionado ao erro que recebo na atualização:

Eu tentei reinstalar o conjunto de chaves: %código% (o que surpreendentemente não causa um aviso).

    

Answer 1

Tente isso, por favor:

Abra um terminal e execute os seguintes comandos:

sudo apt-get clean
sudo rm -rf /var/lib/apt/lists/*
sudo apt-get clean
sudo apt-get update

    

Answer 2

Depois de ler a resposta do APZ , mas querendo usar o aptitude eu executei com sucesso o seguinte comandos:

# clean the obsolete cache
sudo aptitude clean
# update the package information
sudo aptitude update
# install or upgrade the packages
sudo aptitude install <list of packages to upgrade/install>

O erro provavelmente está relacionado ao conteúdo do cache do apt obsoleto, mas a mensagem de erro que recebi foi um pouco diferente:

WARNING: untrusted versions of the following packages will be installed!

    

Answer 3

Você parece ser atingido pelo bug do Debian # 657561 . Você pode tentar mover arquivos problemáticos em / var / lib / apt / lists / * InRelease e re-executar o apt-get update.
