[Carlos Jose Ricotta]

I am using Ubuntu 20.04 in Portuguese - Brazil.
When a try to open LibreOffice Help, I receive a error message in Portuguese: "O objeto não acessível. O objeto não pode ser acessado devido a falta de direitos do usuário".
Translating this message to english: "the object is not accessible. the object cannot be accessed due to lack of user rights.".
