When running the command "guix pull && guix package -i python@2 python"
instead of installing the latest version of python2 and python3, as it
used to do until about four weeks ago, guix gives following error
message (hash values replaced with ...):
guix package: error: profile contains conflicting entries for python:out
guix package: error: first entry: python@2.7.13:out
/gnu/store/...-python-2.7.13
guix package: error: second entry: python@3.5.3:out
/gnu/store/...-python-3.5.3
This error could be reproduced in a VM created with guix system vm-image
and following config file:
(use-modules (gnu) (gnu packages) (gnu system nss))
(use-service-modules desktop xorg)
(use-package-modules certs gnome xdisorg lisp)
(operating-system
(host-name "Test")
(timezone "Europe/Zurich")
(locale "de_CH.UTF-8")
(bootloader (grub-configuration (device "/dev/sda")
(timeout 1)))
(file-systems (cons (file-system
(mount-point "/")
(device "/dev/sda1")
(type "ext4"))
%base-file-systems))
(users (cons (user-account
(name "user1")
(comment "User")
(group "users")
(supplementary-groups '("wheel" "audio" "video"))
