Ubuntu 14.04 não instalando, erro popup ??? em "onde você está?" [fechado]

Question

Estou com um problema ao tentar instalar o Ubuntu 14.04.

Ao inicializar o CD, eu seleciono "Install Ubuntu", o que é bom, mas o problema ocorre toda vez que eu chego no "onde você está?" tela ao escolher sua localização geográfica.
Eu seleciono minha localização e sempre recebo um pop-up com a seguinte mensagem de erro: ??? ???

Literalmente, isso é tudo que mostra! Eu tentei instalar usando um stick USB também e a mesma coisa ocorre no mesmo bit. Também acontece também em 13.10.

Sempre que seleciono OK na mensagem de erro, estou voltando ao início da instalação novamente.

Alguma idéia?

Estou usando um HP Microserver N40L.
