I have switched to a new computer, and need to re-install QGIS 2.8. I imagine some database changes have happened since I last installed it, because now, even though I direct installation to the http://qgis.org/debian-ltr (2.8) repository, it still assumes that sudo apt-get install qgis is meant for 2.10. The 2.10 repository is http://qgis.org/debian. I have installed 2.8 many times before with this same method, so I'm pretty baffled as to what's going on.
Proof of my repository:
I run sudo apt-get install qgis python-qgis and get this error:
The following packages have unmet dependencies: python-qgis : Depends: python-qgis-common (= 1:2.8.3+20trusty) but 1:2.10.1+20trusty is to be installed qgis : Depends: qgis-providers (= 1:2.8.3+20trusty) but 1:2.10.1+20trusty is to be installed Depends: qgis-common (= 1:2.8.3+20trusty) but 1:2.10.1+20trusty is to be installedI have the 2.8 repository set, but for some reason the install qgis command looks for the 2.10 repository instead. When I set the repository to http://qgis.org/debian, it goes ahead and installs 2.10. What is going on here?
