Finally due to the problems of transfer of text between the VM and the Host I prefer to try installing sagemath on a PC W10 and UBUNTU in double boot mode. I will switch to Ubuntu when I want to use SageMath What's wrong ?

jpo@jpodesktop:~/Téléchargements$ cd SageMath/

jpo@jpodesktop:~/Téléchargements/SageMath$ ./sage

Rewriting paths for your new installation directory

This might take a few minutes but only has to be done once.

This is not supported, and Sage will not work. To install Sage from a binary package:

Open the .tar.bz2 archive (or .dmg on OSX)
Move the SageMath folder/app to where you want it to be. You can also rename the directory now.
Start sage for the first time. This will then automatically patch paths in binaries.

After starting Sage for the first time you cannot change the installation any more. To install Sage elsewhere, start over from the binary package. Or recompile Sage from scratch in the new location ("make distclean && make")

Try for instance to find a deb file and install using it. Or use a ppa, e.g.

https://launchpad.net/~aims/+archive/ubuntu/sagemath

thank you dan_fulea I have a little softened my sentence as you can see below. now when I enter the command :sudo apt-get update

I get:

The repository 'http://ppa.launchpad.net/aims/sagemath/ubuntu zesty Release' does not have a Release file.

as I did not get answer this morning I also post about my PB On Ubuntu Forum Sorry

This is just a comment, it reflects my experience and does not directly answer the question. Ubuntu is a great linux distro, but has its own limitations. Users expect a high compatibility of the packages, they get it in 99% of all cases, and the Ubuntu devel team realizes a hard task to put the packages work together. Unfortunately, the wide variety of the sagemath software bundled together makes it impossible to still have full compatibility. Ubuntu 12 & 14 were perfectly working with the ppa. Beginning with Ubuntu 16 there were some install problems. I remember that i had also to declare the "previous name" in the repository - just like the answer on the Ubuntu forum posted above. (Now: Replace zesty -> yakkety .) Then it worked for a long time.

Continuation: Because of this, now i am running manjaro linux, it is a distro with good French support https://fr.wikipedia.org/wiki/Manjaro_Linux and provides a quick access to Arch-Linux, and to the Arch User Group (AUR) repositories. (Without the need to really know everything about details.)

Sagemath could be installed last days on my machine by one click from AUR. This is simply great! (In Arch every user is and has to be actively responsible for the own package dependencies. With this strategy sage has better chances to get updated and resolve all dependencies. And the Arch interest in a sagemath portability is visibly stronger than the effort in the Ubuntu world.

The page

https://launchpad.net/~aims/+archive/ubuntu/sagemath

has a Signing Key / a finger print. (Use it via apt-key to get rid of the error.) Some lines above there is a line:

Display sources.list entries for:

And the drop down list does not offer zesty yet. But yakkety is present.

precedently I tried this (failed too !!)

(PC mode dual boot W10 and Ubuntu 17.04). I installed Sage with this command:

sudo apt install sagemath-common Lecture des listes de paquets... Fait Construction de l'arbre des dépendances Lecture des informations d'état... Fait sagemath-common is already the newest version (7.4-7ubuntu1). 0 mis à jour, 0 nouvellement installés, 0 à enlever et 7 non mis à jour.

It seems that the first problem you've encountered is due to unpacking the binary archive in the directory Téléchargement, the name of which contains non-ascii characters. The solution is simply to move the archive to another location (e.g. your home directory) before unpacking it. More precisely, to install the latest stable version of SageMath under Ubuntu, type the following in a console:

cd 
mv Téléchargements/sage-7.6-Ubuntu_16.04-x86_64.tar.bz2 .
bunzip2 sage-7.6-Ubuntu_16.04-x86_64.tar.bz2
tar xvf sage-7.6-Ubuntu_16.04-x86_64.tar
cd SageMath
./sage -n jupyter
