I am with ubuntu 12 and Qgis 1.8. I have installed QGIS and grass plugin but I can't install python plugin. How to install python plugin with dependeny in Ubuntu?

~$ sudo apt-get install python-qgis

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 python-qgis : Depends: python-qt4 (>= 4.1.0) but it is not going to be installed

  • I think this might be because not all of the packages requested are present in the repository. It's happened to me using the package manager, if you wait a day and then try again you might have better luck. N. – nhopton Sep 12 '12 at 10:18
  • @nhopton its 4th day :( already tried installing dependency it asks for another dependency in chain... – kinkajou Sep 12 '12 at 10:34
  • Then I'm stuck I'm afraid. If you try installing QGIS using the package manager do you get the 'Partial Download' warning? – nhopton Sep 12 '12 at 11:25
  • Hi, are you using the ubuntugis repository? check here for a similar problem and how to add a new repository: http://gis.stackexchange.com/questions/33252/qgis-how-to-change-gdal-version/33267#comment44703_33267 – s_a Sep 12 '12 at 13:05
  • just a thought: have you tried sudo apt-get build-dep python-qgis ??? – s_a Sep 12 '12 at 13:21
  • If you try to install python-qgis by itself, you'll run into a weird libcurl dependency, where the version of libcurl4 the rest of your system depends on has to be uninstalled and a new version installed. Apparently, this has to do with licensing issues. The best way to get python-qgis is to install QGIS from the QGIS repos (as RK suggests below), because they include versions of all the required libraries that are compiled against the version of libcurl4 used in Ubuntu. Welcome to dependency hell. – L_Holcombe Oct 13 '12 at 08:14

Which repository are you using? You might want to add the following to you /etc/apt/sources.list

deb http://qgis.org/debian-nightly precise main
deb-src http://qgis.org/debian-nightly precise main

After that, update your system

apt-get update

Next, add the qgis public key to our package manager's key ring

gpg –keyserver keyserver.ubuntu.com –recv 1F9ADD375CA44993
gpg –export –armor 1F9ADD375CA44993 | sudo apt-key add -

Then try installing again.

sudo apt-get install python-qgis
