Package sagemath-upstream-binary is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'sagemath-upstream-binary' has no installation candidate
Comment surmonter?
UPDATE
Vérifier la commande

Actuellement, le PPA de Sage ne publie un package binaire que pour les systèmes 64 bits:
$ grep '^Package' /var/lib/apt/lists/ppa.launchpad.net_aims*_Packages
/var/lib/apt/lists/ppa.launchpad.net_aims_sagemath_ubuntu_dists_trusty_main_binary-AMD64_Packages:Package: sagemath-upstream-binary
/var/lib/apt/lists/ppa.launchpad.net_aims_sagemath_ubuntu_dists_trusty_main_binary-AMD64_Packages:Package: sagemath-optional
/var/lib/apt/lists/ppa.launchpad.net_aims_sagemath_ubuntu_dists_trusty_main_binary-i386_Packages:Package: sagemath-optional
La page PPA de ce paquet ne répertorie que AMD64
dans la section Constructions.
Même dans une machine virtuelle, il n'y a aucune raison de ne pas utiliser 64 bits. Installez donc Ubuntu 64 bits.
