So far I have found instructions on stack exchange but they are for windows. And so far the information I have found is for windows. I currently have Ubuntu 13.04 Raring tail. I am using qgis 1.8. I understand that gdal automatically comes with it and I should be able to open it(.gdb). I have the .gdb file on my computer. I have tried add vector layer and source type as file and Database and directory. The option for database wants to me connect to a server but I don't need to.
I tried to install ubuntu gis ppa, the stable and unstable version, this actually caused qgis to lost the python plugin option and I have to do a clean uninstall. sudo apt-get remove --purge qgis
I did read this on stackexchange: Migrating geodatabase data into PostGIS without Esri apps?
This maybe my answer but does he mean put that in the terminal?
