[Ludovic Courtès]

Hello,

The ‘jupyter’ package is currently uninstallable:

--8<---------------cut here---------------start------------->8---
$ guix time-machine --commit=40a729a0e6f1d660b942241416c1e2c567616d4d -- 
install -p /tmp/test-profile-for-jupyter jupyter --no-grafts
guix install: warning: Consider running 'guix pull' followed by
'guix package -u' to get up-to-date packages and security updates.

The following package will be installed:
   jupyter 1.0.0
