[Qgis-user] QGIS on Ubuntu 20.04

[Newcomb, Doug]

Hi,

>Hi! Thanks for incluiding me.


>I changed from Ubuntu 18.04 to Ubuntu 20.04, so I automaticly lost the qgis
>software. When I tryed to install it again, many troubles came out, like
>"qgis needs 'this' or 'this' but its not going to be install" or 'its going
>to install 'this' in stand of 'this'; "E: the package its not found" and
>also "you have broken packages". I tryed to erase old packages, tryed to
>clean caché, tryed commands like "autoremove", "autoclean", "sudo apt-get
>-f install' and i followed all the suggested steps from the qgis original
>tutorial but nothing worked!
I have a virtual instance of Ubuntu 20.04 installed on my home computer and have successfully installed 3.10.4 from the standard Ubuntu 20.04 repositories.  I suspect that you have different libraries and versions of QGIS left over from your 18.04 installation and it may be complicated by the possibility that you may have used the UBUNTU GIS PPA to install your previous version.    Hard for me to tell without more detail.

I would suggest that you use aptitude search to find all instances of gdal, grass, proj, and qgis that you may find and remove them with apt.  Then start with a simple qgis installation using apt.

>Please, anything will help, i'm in the middle of my final work to get a

You can also make a virtual instance of 20.04  ( using KVM) and install qgis there.  I nfs mapped my base systems drives to the virtual instance to access my data on the base system.

>Thanks for your atention!

Good luck!
