upgrade qgis to 1.7.2 breaks python (using ubuntugis-unstable repos)

[etourigny]

This issue has been discussed recently on the qgis-user mailing

"Critical problems with 1.7.2 from ubuntu binaries" list.http://lists.osgeo.org/pipermail/qgis-user/2011-November/014535.html

After updating to 1.7.2 in ubuntu 10.4 LTS using the
ubuntugis-unstable repo, the CRS cannot be set:
"Could not open CRS database /resources/srs.db<br>Error(14): unable to
open database file!

and almost all plugins are gone (including plugin installer).

I also had the same problem, using Ubuntu 11.04

It seems the workaround is to uninstall QGis and re-install.

The following packages were around (even after the re-install)

 dpkg -l | grep qgis

ii  qgis-providers                                    1.7.2-1~natty1                                    collection of data providers to Quantum GIS

A possible fix would be ro remove old libqgis-1.7.x packages (marking them as conflicting), or better yet only have one libqgis package. There is no need to keep various versions of libqgis, as this causes a conflict in the python bindings.

Apparently nobody handles Trac tickets any more, closing this ancient issue.
