[QGIS-Developer] QGIS 3 on Ubuntu 17.10 uninstallable?

[Patrick Dunford]

These messages tell me this is an upgrade rather than a clean install. 
Packages already installed on your system are of versions that can only 
be upgraded to 3.1 (development release) because these existing packages 
are a development release like 2.99 or 3.1. They do not install because 
you have pointed apt at the stable repositories so they are not 
available in those repositories.

If you have only uninstalled some packages you need to remove the ones 
that are generating these error messages.

When you change repos the messages change because you are installing a 
different version of Qgis and it needs different packages and apt will 
still run into the same problem that the packages already in the system 
are development release and can only be upgrade to another development 
release and do not match the stable release.

Uninstall python-qgis, qgis-providers etc. Do an apt autoremove if there 
is a list of packages that are no longer needed because it will probably 
include a lot of qgis related packages.
