[conda] conda update and Jupyter -- strange behavior

[a***@gmail.com]

This is kind of strange. Conda does not show any updates but when I try to
install Jupyter it says some packages need to be updated and it will do the
update. Why this behavior ?

[***@arch64 ~]$ conda update conda
Solving environment: done

# All requested packages already installed.

[***@arch64 ~]$ conda update --all
Solving environment: done

# All requested packages already installed.

[***@arch64 ~]$ conda install jupyter
