The solution that I found for installing qgis (Quantum GIS) on LMDE (Linux Mint Debian Edition) is not optimal, but the only one that worked for me.
I am getting QGIS directly from the QGIS Debian repository and I am temporarily adding the main debian repository to my sources, because QGIS depends on some packages that are not included in LMDE.
LMDE: Install QGIS
Add QGIS to your sources.lst:
sudo vim /etc/apt/sources.list # add: deb http://qgis.org/debian/ jessie main deb http://ftp.us.debian.org/debian/ jessie main
After this, do not call apt-get upgrade until you removed these lines.
Now you can install QGIS:
sudo apt-get update sudo apt-get install qgis
And at last remove the added lines from your sources.lst.
sudo vim /etc/apt/sources.list # remove: deb http://qgis.org/debian/ jessie main deb http://ftp.us.debian.org/debian/ jessie main sudo apt-get update
This step is important, as otherwise a call to apt-get upgrade could break your system.
That’s it, now QGIS should run on your installation of LMDE.
