Hi Gloria, Not sure if you can pull up to 3.10 on Debian Stretch/9 (which is rather old....).
If I look here: https://qgis.org/debian/dists/stretch/main/binary-amd64/Packages it looks like that if you try to install QGIS in the normal/distro way, you will end up with QGIS 3.4 (I think, anybody can confirm ...) Isn't it possible to upgrade your machine to Debian 10/Buster? Then you can upgrade to 3.12 (which is 3.10 plus a little extra ;-) ) if you use the "Démarrage rapide" https://www.qgis.org/fr/site/forusers/alldownloads.html#quickstart Or even 3.14, 3.16 (tell your educator there is a newer LTR ;-) ) or higher? If all fails, you could try to install a flatpak (but not sure about that either for Debian 9): https://www.qgis.org/fr/site/forusers/alldownloads.html#flatpak And if even that fails... and you have some experience with compiling yourself, you could compile from source... But: Stretch is rather old, if you ask me: upgrade to Buster/10 first Good Luck & regards, Richard Duivenvoorde On 2/23/21 11:23 AM, SENFAUTE Gloria wrote: > Dear all, > > In case, you can write in French! > > I need a strong help for updating or installing last version of QGIS. > > Working in linus (Debian GNU/Linux 9 (stretch) 64 bits). > > In my computer I have a version of QGIS (2.4 ESSEN). > > In few days I will have my first training with QGIS and I must to install: > QGIS 3.10.14 LTR. > > > > I would like to know what is the better way: > > 1)To update of QGIS 2.4 to 3.10.14 LTR, *How to do it* ? > > 2) To remove QGIS 2.4 and then re-install following the steps of QGIS site > for linus ? > > I am so afraid of this last solution: if I remove and I cannot install the > new QGIS. > > I administrator of my computer but I have also many proxis installed by my > company, so I didn’t try, I am waiting for advises. > > > > Thank you very much ! > > > > Gloria > > > > > > > > > > > > > > *Gloria SENFAUTE* > *Ingénieur Chercheur, PhD* > Expert Aléa Sismique > Département Electrotechnique et Mécanique des Structures - ERMES > Groupe Séisme et Impacts, EDF Lab Paris-Saclay > 7 Boulevard Gaspard Monge > 91120 Palaiseau > > > > *gloria.senfa...@edf.fr* > > Tél. : 33 1 78193433 > > > > > > Un geste simple pour l'environnement, n'imprimez ce message que si vous en > avez l'utilité. > > > > > Ce message et toutes les pièces jointes (ci-après le 'Message') sont établis > à l'intention exclusive des destinataires et les informations qui y figurent > sont strictement confidentielles.
