QGIS 3.0 is out and from the blogs and tweets, it looks awesome. Some one asked me how to install QGIS 3.0 on Ubuntu 16.04, so here are the steps.
First, if you have previous version of qGIS, lets delete that
sudo apt-get autoremove qgis sudo apt-get --purge remove qgis python-qgis qgis-plugin-grass sudo apt-get autoremove
Now edit /etc/apt/sources.list by using the following command
sudo vi /etc/apt/sources.list
Note: Sudo is required because normal users do not have rights in /etc/apt/ folder.
Now this is where is trick is, instead of adding debian or ubunutgis repositories add ubunutgis-nightly-release, so add the following two lines in source. list
deb https://qgis.org/ubuntugis-nightly-release xenial main deb-src https://qgis.org/ubuntugis-nightly-release xenial main
Rest is simple, first update
sudo apt-get update
and then install
sudo apt-get install qgis python-qgis qgis-plugin-grass saga
Some of the dependencies will not be there if we use ubuntugis-nightly-release repository reference.
