failed
UnsatisfiableError: The following specifications were found to be incompatible with each other:
Package clangdev conflicts for:
xeus-cling -> cling[version='>=0.6,<0.7.0a0'] -> clangdev=5.0.0
Note that strict channel priority may have removed packages required for satisfiability.
Tentative analysis
Jupyter/scipy-notebooks fixes the version of all the packages it installed. Presumably they had not been updated in a while, and xeus-cling/cling required a more recent version of a few of them.
Solution
With 98877fb5 , conda updates all installed packages before installing the packages of the other repositories. This seems to do the job.
