I have got a problem with my QGIS on a trusty 14.04.01. After upgrading my machine from precise 12.04 to trusty 14.04, QGIS was disappeared from the available software. I have autoremoved it and removed the PPAs from the source.list as instructed here successfully. However, when I try to run the new sudo apt-get install QGIS I am getting the following dependency errors and I kinda stuck here.

I run pgres 9.3 and postGIS 2.2 without any problem but when I try to install Qgis I fail all the time.

Any thoughts or a workaround will be appreciated!

It took me a while to figure out what went wrong. You will see it in the last line of my sources.list. Therefore, if you have got the same problem as me then what you need to do is to follow this wiki.

Then, you will have to make sure that all the ubuntugis or qgis dependencies from the etc/apt/sources.list.d are removed. The code will look like sudo rm /etc/apt/sources.list.d/ thegisfile

Finally, follow the instructions to install QGIS from here and you are done!

  • Thanks for posting this. What do you mean with "You will see it in the last line of my sources.list"? Is this the original output or how you modified it, to be sure? I have the same problem as yours but I don't see those lines in my /etc/apt/sources.list. Who did what around those lines? Dec 9, 2016 at 21:31
