je dois installer la carte d'examen dans ubuntu, j'ai essayé de suivre les commandes mais je reçois une erreur
sudo apt-get install python-setuptools.
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package python-setuptools 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 python-setuptools has no installation candidate
Ensuite, j'ai essayé la commande ci-dessous, mais pour cela, je reçois également un message d'erreur:
apt-get upgrade
E: Could not open lock file /var/lib/dpkg/lock - open (13 Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
Que devrais-je faire? Sil te plait aide moi!!!!!
