Estou tentando instalar o Qt5.3 no meu Ubuntu 14.04 (64 bits). Enquanto o processo de instalação estava sendo executado de repente, ele mostrava alguns prompts e mostrava várias mensagens de erro da seguinte forma:
Error during installation process (qt.53.doc):

QMake from the current Qt version
(/opt/Qt5.3.1/5.3/gcc_64/bin/qmake)is not existing. Please file a bugreport with this dialog at https://bugreports.qt-project.org.
Para o primeiro erro "'installer: //qt.53.doc/5.3.1-0qt5_docs.7z': Não foi possível abrir o arquivo", verifiquei se há 7zip instalado na minha máquina ou não..Mas 7zip foi instalado. Eu não posso reconhecer os outros erros.
Como faço para corrigir isso?
