nano-default-editor is missing following 'dnf system-upgrade' Fedora 32 to Fedora 33. $ cat /etc/fedora-release Fedora release 33 (Thirty Three)
$ cat /etc/os-release | grep PRETTY PRETTY_NAME="Fedora 33 (Workstation Edition Prerelease)"
Ohh, nice. That explains it. https://fedoraproject.org/wiki/Changes/UseNanoByDefault#Upgrade.2Fcompatibility_impact
Of course, it will magically become the default editor in the future when bug #1845562 is fixed.
