Sto cercando di installare python-dev su un guest Ubuntu 16.04 LTS (64 bit) in esecuzione su un host Windows. Ho provato a installare usando apt-get e poi tramite aptitude, ma mi sembra di riscontrare degli errori.
~$sudo aptitude install python-dev
dà,
The following NEW packages will be installed:
libexpat1-dev{ab} libpython-dev{a} libpython2.7-dev{ab} python-dev python2.7-dev{ab}
0 packages upgraded, 5 newly installed, 0 to remove and 0 not upgraded.
Need to get 28.2 MB of archives. After unpacking 42.1 MB will be used.
The following packages have unmet dependencies:
python2.7-dev : Depends: python2.7 (= 2.7.11-7ubuntu1) but 2.7.12-1~16.04 is installed.
Depends: libpython2.7 (= 2.7.11-7ubuntu1) but 2.7.12-1~16.04 is installed.
libexpat1-dev : Depends: libexpat1 (= 2.1.0-7) but 2.1.0-7ubuntu0.16.04.2 is installed.
libpython2.7-dev : Depends: libpython2.7-stdlib (= 2.7.11-7ubuntu1) but 2.7.12-1~16.04 is installed.

The following actions will resolve these dependencies:
Keep the following packages at their current version:
1) libexpat1-dev [Not Installed]
2) libpython-dev [Not Installed]
3) libpython2.7-dev [Not Installed]
4) python-dev [Not Installed]
5) python2.7-dev [Not Installed]

come uscita. Considerando che,
~$sudo apt-get install python-dev

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:
The following packages have unmet dependencies:

Ho eseguito sudo aptitude update e sudo aptitude upgrade , ma questo non risolve il problema.
Inoltre, ho eseguito i passaggi indicati nei seguenti collegamenti:
- Impossibile installare python-dev
- Come faccio a risolvere le dipendenze non soddisfatte dopo aver aggiunto un PPA?
ma nulla sembra funzionare.
Dal messaggio di aptitude, penso che le dipendenze installate sul mio sistema siano di una versione superiore a quella richiesta dal pacchetto (ad esempio, un messaggio dice Depends: libpython2.7 (= 2.7.11-7ubuntu1) but 2.7.12-1~16.04 is installed. ).
Immagino che le mie opzioni siano a,
- disinstallare i pacchetti esistenti (cosa che preferirei non), oppure
- aggiungi un PPA più aggiornato per Python-stuff.
I miei repository attuali sono:
~$egrep -v '^#|^ *$' /etc/apt/sources.list /etc/apt/sources.list.d/*
/etc/apt/sources.list:deb http://us.archive.ubuntu.com/ubuntu/ xenial main restricted
/etc/apt/sources.list:deb http://us.archive.ubuntu.com/ubuntu/ xenial universe
/etc/apt/sources.list:deb http://us.archive.ubuntu.com/ubuntu/ xenial multiverse
Qualche idea su come posso installare python-dev?
Grazie in anticipo!
Risposta accettata:
Una delle mie nuove installazioni ha questi repository. Sembra che manchi qualche update archivi.
Ho inserito * stelle a quelli che non vedo dalla tua lista.

Prova almeno ad aggiungere l'update repository... quindi esegui:
$ sudo apt update
$ sudo apt upgrade
