Qsci cannot be imported (breaks Eric) after installing Kubuntu backport to Jaunty

[Stephen Boddy]

Binary package hint: python-qt4

After installing Kubuntu backport which includes python-qt4 - 4.5.2-0ubuntu1~jaunty2 + friends, it is no longer possible to "from PyQt4 import Qsci" (Qsci being the scintilla editing component). This breaks Eric (obviously) and it fails to start.
Running it from the command line gives the following traceback:

XXXX@XXXX:~/Desktop$ eric
Traceback (most recent call last):
  File "/usr/share/eric/modules/eric4.py", line 43, in <module>

    import Preferences
  File "/usr/share/eric/modules/Preferences/__init__.py", line 26, in <module>
    from PyQt4 import Qsci
ImportError: cannot import name Qsci

The QSci files are there:

Temporary Workaround: I managed to get Eric working by installing the Karmic versions of the following packages with "deb -i *.deb":

libqscintilla2-5_2.4-3_i386.deb
libqscintilla2-designer_2.4-3_i386.deb
libqscintilla2-dev_2.4-3_all.deb
libqscintilla2-doc_2.4-3_all.deb
python-qscintilla2_2.4-3_i386.deb
python-support_1.0.3ubuntu1_all.deb

Warning: might break other things :-) This was a result of hacking around.

@ francois: I have the same version of python-qt4 as you do, and am also missing the files you list, but eric works for me with the workaround in my #1 comment. Have you tried the workaround, and did it work?

You need to download the packages manually and install them.

[francois (francois-beaubert)]

Hi Stephen

Thanks for your kind answer.
I haven't tried your workaround yet but I plan to try it soon.
But I think I really need those files for spyder

Anyway thank you very for your help!
Cheers

I encountered the same problem when I tried to re-install eric 4.3.6 after upgrading ibex to jaunty. For some reason the python-qscintilla2 package was present before the upgrade, but not present after the upgrade. All I needed to do to fix the problem was to use Synaptic to install the python-scintilla package and try to do the install again.

Attached are the "selections" from dpkg from the ibex system before the upgrade, and from the jaunty system after getting eric 4.3.6 to install. Also attached is the log of the reinstall of eric.

By the way, the eric dpkg in the repository is way out of date. Eric recognizes that a more recent version is available, but the official one needs to be uninstalled and you need to go behind Synaptic's back to get the current version and install it. Life with Ubuntu should be better than that.

This is fixed in more recent releases.
