QGIS 2.4 is in the default repos. UbuntuGIS only seems to support LTS releases. I tried to follow the directions on the QGIS website here but something is not working because I still only have QGIS 2.4.
Is there some way I can install QGIS 2.8 on Ubuntu 15.04?
I figured it out. First UbuntuGIS appears to only support LTS releases. I ended up not using or needing UbuntuGIS.
To install the newest version of QGIS I added the QGIS repositories to my /etc/apt/sources.list file:
sudo nano /etc/apt/sources.list
and inserted these lines:
deb http://qgis.org/debian vivid main
deb-src http://qgis.org/debian vivid main
Remember to add the GPG keys as follows:
gpg --keyserver keyserver.ubuntu.com --recv 3FF5FFCAD71472C4
gpg --export --armor 3FF5FFCAD71472C4 | sudo apt-key add -
Then run:
sudo apt-get update
sudo apt-get install qgis python-qgis qgis-plugin-grass
This installed qgis 2.10.1
At some point it should be possible to install from the ubuntugis repository instead of the debian repository following the instructions at https://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu. These instructions here do at present not install QGIS 2.10 for Ubuntu 15.04, but they work for Ubuntu 14.X
The reason seems to be simply that this location http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu does not yet contain a version for Ubuntu 15.04 (vivid), as can be seen browsing through the available versions.
