Note that this istestable from Mock, if you are not running Fedora 26 yet. All you need to do is to create a mock config with updates-testing.
cp /etc/mock/fedora-26-x86_64.cfg /etc/mock/fedora-26-x86_64-testing.cfg
mock -r fedora-26-x86_64-testing --init mock -r fedora-26-x86_64-testing --install \ notebook ipython2 python2-ipykernel mock -r fedora-26-x86_64-testing --shell
I see "Python detected LC_CTYPE=C: LC_ALL & LANG coerced to C.UTF-8 (set another locale or PYTHONCOERCECLOCALE=0 to disable this locale coercion behaviour)." as described. Click works. Python3 works. Dnf works.
