Quando ho provato a installare python3-dev
usando sudo apt-get install python3-dev
ho ricevuto il seguente messaggio
python3-dev : Depends: libpython3-dev (= 3.4.0-0ubuntu2) but it is not going to be installed
Depends: python3.4-dev (>= 3.4.0-0~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Quindi ho provato a installare le dipendenze libpython3-dev
e ho ricevuto questo messaggio
The following packages have unmet dependencies:
libpython3.4-dev : Depends: libpython3.4-stdlib (= 3.4.0-2ubuntu1.1) but 3.4.3-1ubuntu1~14.04.1 is to be installed
Depends: libpython3.4 (= 3.4.0-2ubuntu1.1) but 3.4.3-1ubuntu1~14.04.1 is to be installed
E: Unable to correct problems, you have held broken packages.
Tuttavia entrambe le dipendenze sono già installate. Sto usando Ubuntu 14.04
Quando ho corso l' apt-cache policy python3.4
ho ottenuto
python3.4:

sudo apt-get clean all
apt-get clean all
quindi riprova.
