[Qgis-user] QGIS 3 installation on Ubuntu

[Patrick Dunford]

Hi there
The core development of Qgis is on Linux so it is very well supported on 
that platform. In answer to your specific questions:
* Use the latest stable version of Ubuntu (18.04) - variants like 
Lubuntu, Xubuntu etc also work well and may be more suited to specific 
requirements.

1. The repositories labelled "debian" are for both Debian and Ubuntu - 
you specify the release name in the deb statement which supports release 
names for both distros.

2. You need to check error messages from the apt command if you get an 
error when installing from an https repository. For example you may need 
to install the package apt-transport-https to enable apt to work with 
https repositorities. This is not an issue with the repository, it is an 
issue with apt. The error message in this case is pretty descriptive as 
to what is needed.
