SO:Ubuntu 14.04
He visto una pregunta similar, pero ninguno de los métodos mencionados allí funciona.
Instalé python 3.5 ejecutando:
apt-get install -y software-properties-common && \
add-apt-repository ppa:fkrull/deadsnakes && \
apt-get update
apt-get install -y python3.5 python3.5-dev
Cometí un error al ejecutar ln -sf /usr/bin/python /usr/bin/python3.5 , por lo que el enlace simbólico a python3.5 convertirse en python2.7 .
He probado:
1.
rm -f /etc/apt/sources.list.d/*
dpkg --configure -a
add-apt-repository ppa:fkrull/deadsnakes
apt-get update
apt-get install --reinstall python3.5 python3.5-dev
2.
apt-get remove --purge python3.5 python3.5-dev
apt-get install python3.5 python3.5-dev
En ambos casos obtuve algo como:
/var/lib/dpkg/info/python3.5.postinst: 9: /var/lib/dpkg/info/python3.5.postinst: python3.5: not found
dpkg: error processing package python3.5 (--configure):
subprocess installed post-installation script returned error exit status 127
dpkg: dependency problems prevent configuration of python3.5-dev:
python3.5-dev depends on python3.5 (= 3.5.2-1~trusty1); however:
Package python3.5 is not configured yet.
dpkg: error processing package python3.5-dev (--configure):
dependency problems - leaving unconfigured
Errors were encountered while processing:
python3.5
python3.5-dev
E: Sub-process /usr/bin/dpkg returned an error code (1)
Respuesta aceptada:
Lo arreglé.
Encuentra todas las dependencias:
dpkg -l | grep python3.5
Eliminarlos todos:
apt-get --purge remove libpython3.5 libpython3.5-dev libpython3.5-minimal libpython3.5-stdlib python3.5 python3.5-dev python3.5-minimal
Reinstalar
apt-get install python3.5-dev
