/etc/os-release says raspbian 10 (buster)
pi 3
i know this worked previously, because i originally set up the whole pi using nano. but now, every time i open nano, any file, no file, sudo, or not, i get "illegal instruction" and nothing else. i have uninstalled and reinstalled nano with
sudo apt-get remove nano
sudo apt-get install nano
nano --version says 3.2
behavior persists.
