Encontrado este link em [this AskUbuntu][2]
question;
Simplesmente executei este comando e tudo voltou ao normal;
find ~/.steam/root/ -name "libgpg-error.so*" -print -delete
Obrigado a todos pela ajuda.
Eu pesquisei e também verifiquei algumas perguntas no AskUbuntu sem qualquer sorte.
Aqui está o que recebo quando executo steam
no console;
