I can't install python-openssl, code: /home/user # apt-get install python-openssl Reading package lists... Done Building dependency tree Reading state information... Done Package python-openssl 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-openssl has no installation candidate The python-setuptools installation went OK (I guess). Any ideas?
