[michel83]

Hi, trying to install : http://www.geogebra.org/download/deb.php?arch=amd64&ver=6 (http://http://www.geogebra.org/download/deb.php?arch=amd64&ver=6)
I get an error message : libmpfr4 is needed but can't be installed

Hello

Your link is broke and libmpfr4 has been dropped in 18.04.

https://packages.ubuntu.com/artful/libmpfr4

Thanks for the answer and sorry for the link, better with : https://wiki.geogebra.org/en/Reference%3AGeoGebra_Installation#Other_GeoGebra_C lassic_6_versions (https://wiki.geogebra.org/en/Reference%3AGeoGebra_Installation#Other_GeoGebra_C lassic_6_versions) ?
and in this page : Linux (deb): 64 bit

Looks like GeoGebra needs to be upgraded, I would post in their forum.

Good luck

Hold on

Its in our software


sudo apt install geogebra-gnome

Thanks, but geogebra-gnome is a very old version 4.0.34 and not the 6 and even 5. With your link, i could install libmpfr4 from :
https://packages.ubuntu.com/fr/artful/amd64/libmpfr4/download
http://fr.archive.ubuntu.com/ubuntu/pool/main/m/mpfr4/libmpfr4_3.1.6-1_amd64.deb and after, I could install GeoGebra 6 (geogebra-classic) and it works fine. Thanks again.
