You should at least:

apt remove qgis python-qgis qgis-plugin-grass

apt autoremove

apt update

apt install qgis

then see what messages you get.


or type "sudo apt-cache policy qgis".

If you are using Windows you can install alongside a previous version by 
placing it in a different path.


If using Linux the below applies as there can only be one installation 
in a system at a time.


The library names may be the same and if so you can get error messages 
that the software needs 3.4 libraries but the system will only provide 
2.12 libraries due to them already being installed previously.


If you see a message like that then manually remove the component that 
requires the library and then use apt autoremove to remove as many 
dependencies as possible


The messages looks something like

/ requires  but it is not going to be installed/

/ requires  but  is installed/

/Unable to install... you have held broken packages./

You should at least:

apt remove qgis python-qgis qgis-plugin-grass

apt autoremove

apt update

apt install qgis

then see what messages you get. Remove additional packages as necessary 
and repeat.

If you are using Windows, you don't need to uninstall 2.12 first.

Best regards
