Este comando só pode ser usado pelo root

Question

Estou no Ubuntu 16 e gostaria de adicionar um pacote neo4j. Eu tentei de 3 maneiras, todas levando ao mesmo erro.

Estas são minhas tentativas:

wget -O - http://debian.neo4j.org/neotechnology.gpg.key | apt-key add -

sudo wget -O - http://debian.neo4j.org/neotechnology.gpg.key | apt-key add -

sudo -i wget -O - http://debian.neo4j.org/neotechnology.gpg.key | apt-key add -

Mas eu sempre recebo esta mensagem de erro:

ERROR: This command can only be used by root.

Answer 1

Você precisa alterar seu comando wget de:

sudo wget -O - http://debian.neo4j.org/neotechnology.gpg.key | apt-key add -

para:

sudo wget http://debian.neo4j.org/neotechnology.gpg.key | apt-key add -

das man pages para wget ...

   -O file
   --output-document=file
       The documents will not be written to the appropriate files, but all
       will be concatenated together and written to file.  If - is used as
       file, documents will be printed to standard output, disabling link
       conversion.

    

Answer 2

A mensagem de erro é de apt-key e, como diz, use-a com sudo :

wget -O - http://debian.neo4j.org/neotechnology.gpg.key | sudo apt-key add -
