mise à jour sageMath

Bonjour,
depuis l'installation de sagemath sous Ubuntu 12.04 j'ai une mise à jour qui renvoie un message d'erreur

installArchives() failed: Setting up sagemath-upstream-binary (5.0.1) ...
Running Sage once as root to set paths
Error: environment variable $HOME is not set.

possibly contact sage-devel (see http://groups.google.com/group/sage-devel).

J'ai essayé d'aller voir le fichier /usr/lib/sage/spkg/bin/sage-env, mais cela dépasse mes (maigres) compétences.
Si vous pouviez m'aider, merci d'avance.

Re : mise à jour sageMath

bonjour,
un petit :
cat /usr/lib/sage/spkg/bin/sage-env
dans un terminal, sinon tu peux aussi demandeer des précisions à https://groups.google.com/forum/?fromgr … sage-devel smile

Re : mise à jour sageMath

En fait, j'arrive à lire le contenu de ce fichier, mais je ne vois pas quoi faire.
Je vais essayer ton groupe, mais c'est en anglais.
