Eu tinha instalado o programa, mas quando quero atualizar, não consegui encontrá-lo

Eu tinha instalado o youtube-dl:

# youtube-dl
Usage: youtube-dl [OPTIONS] URL [URL...]

youtube-dl: error: You must provide at least one URL.
Type youtube-dl --help to see a list of all options.

Mas quando eu executo com --extract-audio --audio-format mp3 [URL], termina com

WARNING: 0g7KawdsVSQ: writing DASH m4a. Only some players support this container. Install ffmpeg or avconv to fix this automatically.
ERROR: ffprobe or avprobe not found. Please install one.

E quando eu quiser atualizar o pacote youtube-dl, para instalar arquivos adicionais:

E quando eu quiser instalar o ffmpeg:

Package ffmpeg is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Alguns detalhes:

  • Usando Kali GNU/Linux 2.0 (sana) de 64 bits.

  • Estou tentando atualizar, com o comando:apt-get upgrade youtube-dl

Estão faltando fontes no seu arquivo sources.list.

VerRepositórios Kali fontes.list, que diz:

Em uma instalação padrão e limpa do Kali Linux, você deve ter as duas entradas a seguir presentes em /etc/apt/sources.list:

deb http://http.kali.org/kali sana main non-free contrib
deb http://security.kali.org/kali-security sana/updates main contrib non-free

Você parece ter a segunda linha, mas não a primeira. Verifique o seu sources.list.
