Como posso corrigir isso?

    

Answer 1

Adicione esta linha a /etc/apt/sources.list :

deb http://archive.canonical.com/ubuntu yakkety partner

e execute

sudo apt update

    

Answer 2

Parece que você está puxando de um repositório antigo.

Vá para Software e amp; Atualizações > Outro software.

Em seguida, remova o antigo repositório chamado:

http://archive.canonical.com/ubuntu maverick partner

Em seguida, ative o repositório 'Canonical Partners' .

Se não existir, clique em adicionar e digite:

deb http://archive.canonical.com/ubuntu yakkety partner

Em seguida, execute:

sudo apt-get install adobe-flashplugin

O Flash Player deve agora ser instalado. Reinicie seu navegador para que as alterações entrem em vigor.
