I updated an Ubuntu 12.04 machine to 14.04.

The 12.04 install just had qt4, and had 

/usr/lib/x86_64-linux-gnu/qt4/bin/designer

The 14.04 install has qt5, but I cannot get a

/usr/lib/x86_64-linux-gnu/qt5/bin/designer executable installed.

I have libqt5designer5 and libqt5designercomponents5 installed, and I get the libs but not the application.

I also have a bunch of qtquick packages installed.

How should I proceed?

sudo apt-get install qttools5-dev-tools

solved the problem.

The designer is included in the package "qttools5-dev-tools".

[$ nbviewer]$ apt-file search /usr/lib/x86_64-linux-gnu/qt5/bin/designer 
qttools5-dev-tools: /usr/lib/x86_64-linux-gnu/qt5/bin/designer

    That worked for me too. It should probably be marked as the answer. – Alexis Wilke May 18 '16 at 07:11
  • Worked also on 16.04. +1 for marking this as the accepted answer. – Peter Apr 06 '18 at 09:04
  • In 16.04 `/usr/bin/designer` is just a symlink to `qtchooser`. It decides by the link name which tool to start. If you have multiple Qt versions installed you can give it one of the versions given by `qtchooser -l`. E.g. `designer -qt5` will open the Qt5 version of designer. – Peter Apr 06 '18 at 09:14

In the library packed are no binaries for the designer application.

Install the designer with

sudo apt-get install qtcreator

  • Hi, thanks very much A.B. qtcreator is installed, and is using qt5. I can open one of their examples, but the design button on left sidebar stays greyed out. --Kate – KateF Jul 23 '15 at 19:49
  • I will check this tomorrow – A.B. Jul 23 '15 at 20:47
  • The button is only active, if there is a open ui-file. I will add a screenshot. – A.B. Jul 24 '15 at 16:39
  • Do you have /usr/lib/x86_64-linux-gnu/qt5/bin/designer on your system ? If so, could you do dpkg -S on it and let me know what pkg it came from ? – KateF Jul 24 '15 at 21:08

    This is not what was asked for and doesn’t help user that use another or no idea at all. Plus it doesn’t even work if `qttools5-dev-tools` isn’t installed, so this basically boils down to @ptmono answer. – Peter Apr 06 '18 at 09:06

I was doing: 

sudo apt-get install qttools5-dev-tools

I was not getting any results so instead I tried this and it worked:

sudo apt-get install qttools5-dev

This little difference has supposed some hours for me, I hope this post will help you.

For anybody who is working on PyQT5 on NVIDIA Jetson Tegra X2 (TX2) running Ubuntu 16.04, this is the directory to find QT5 Designer:

/usr/lib/aarch64-linux-gnu/qt5/bin/designer
