I've update the post to include some more information. Good luck!
#3 B commented on 2008-10-02:
it's somewhat odd, but it seems like the python-qt4 package is missing some parts. specifically, I've run into two so far: setTimeSpec from QDateTimeEdit and setHeaderHidden from QTreeView. Both of these are in the docs, so I guess to use them you need to do a manual install? Unless the next release fixes this.
#4 Eliot commented on 2008-10-02:
python-qt4 package in Ubuntu Hardy provides PyQt 4.3. However, currently, the latest version is PyQt 4.4. You were probably looking at the docs for 4.4. To get the latest version, you can install it manually (I don't think it is very hard). Or, if you can wait a month, Ubuntu Intrepid will include PyQt 4.4.

I'm trying to get Thin Liquid Film running on my Intrepid Ibex installation. However, when I try installing it, it tells me that I'm missing pyqt.
I loaded Synaptic and have installed the python-qt4 package (version 4.4.3-1ubuntu1) which includes the libqtcore package version 4.4.3-0ubuntu1 and python-bindings version 4.4.3-1ubuntu1.
Any ideas why its not installing?

Answering my own question. Apparently TLF is specifically looking for QT3. Guess they haven't updated their program as of yet.

On my ubuntu box, there are python2.6 and python3.1
When I installed PyQt4 it works for python2.6.
How to configure it for python3.1 too?

After trying, the follow appears:
Depende: libqt4-designer (>= 4:4.7.0) mas não vai ser instalado Depende: libqt4-help (>= 4:4.7.0) mas não vai ser instalado Depende: libqt4-scripttools (>= 4:4.7.0) mas não vai ser instalado Depende: libqt4-test (>= 4:4.7.0) mas não vai ser instalado Depende: libqtassistantclient4 (>= 4.6.3) mas não vai ser instalado Depende: sip-api-8.1
After trying to install libqt4 it appears:
Depende: python-qt4 (>= 4.4) mas não vai ser instalado Depende: python-sqlalchemy (>= 0.4.3) mas não vai ser instalado Depende: python-beautifulsoup mas não vai ser instalado Recomenda: python-matplotlib mas não vai ser instalado
So, basically, one depends on the other, and none will install...
Thank you for the tips though...

Worked just fine thank you. Ubuntu 11.1 Wheezy/sid 3.0.0-14-generic-pae i686
#15 Juuso commented on 2012-01-26:
If you are looking for pyqt designer, you should also add: apt-get install libqt4-dev qt4-dev-tools python-qt4-dev pyqt4-dev-tools

I have been trying unsuccessfully on and off for over three months to get eric5 installed on my Ubuntu 11.10 system. Each time I try to compile it, i get the same error msg, "Qthelp not found". I have python2.7 and 3.2 and 3.2mu installed. When i install I have referenced python, python3.2 and python3.2mu, all to no avail. Any help would be greatly appreciated. Tkinter is looking better by the day, though I would really love to use QT and eric5. If I try using apt-get install, it says already installed because they are, for 2.7, but not 3.2. I have BUILT MAKE INSTALLED the QT downloads several times along with SIP, Pyqt, pyside and several other apps, but once again,, nada. I am starting to think it can't be done. in all of my 30 plus years of using building and repairing computers, I have never, ever seen anything as convoluted and aggravating as this. For the love of God if anyone, anywhere has any idea of how to get this %^$&$ thing to work, PLEASE,, let me know...

Quick and easy advice, thanks. Worked first time for me. Ubuntu 10.04.
#18 Ha Thanh commented on 2012-09-09:
Yes, it worked for me. Ubuntu 11.10.
#19 paython commented on 2012-09-21:
We do not need to install sip before install pyqt?
#20 Diego commented on 2012-11-10:
