Error running 'lupdate'.

[drivador]

In the paragraph where you explain how to create a translation, I suggest an auxiliary addendum because in case we don't have all the basis for programming in Qt, the 'lupdate' command ends up in error. So I would quote:
If "lupdate" responds with the error “could not exec /usr/lib/x86_64-linux-gnu/qt5/bin/lupdate: No such file or directory” execute:
$ sudo apt-get install qttools5-dev-tools
