Can not install depends in LM 21

[Brackston]

I tried to install the dependencies to build, however, I receive this error .

sudo apt-get install qtcreator g++ qt5-default libsane-dev libtiff5-dev
cmake libpodofo-dev imagemagick tesseract-ocr tesseract-ocr-eng
libpoppler-qt5-dev Reading package lists... Done Building dependency tree... Done Reading state information... Done Package qt5-default is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

E: Package 'qt5-default' has no installation candidate
