Como posso corrigir isso?

    

Answer 1

Duas questões aqui:

1. Várias configurações, corrija:

   1. /etc/apt/sources.list.d/libreoffice-ubuntu-ppa-xenial.list

      • Abra o arquivo sudo nano /etc/apt/sources.list.d/libreoffice-ubuntu-ppa-xenial.list
      • Coloque um # no início da linha 2 e 3

   2. /etc/apt/sources.list.d/fossfreedom-ubuntu-packagefixes-xenial.list

      • Abra o arquivo sudo nano /etc/apt/sources.list.d/fossfreedom-ubuntu-packagefixes-xenial.list
      • Coloque # no início da linha 2 ou 3

   3. /etc/apt/sources.list.d/xenial-partner.list

      • excluir sudo rm -f /etc/apt/sources.list.d/xenial-partner.list
      • Ou coloque um # no início da linha 19 em /etc/apt/sources.list

   4. Agora execute a atualização: sudo apt update

2. Verifique se a conexão com a internet está correta.
