nanoを消したDebianでエディタの警告が出るのを修正

vim使うのでnanoを消しているのですが警告が出ています．

$ sudo crontab -e
/usr/bin/sensible-editor: 25: /usr/bin/sensible-editor: /bin/nano: not found
/usr/bin/sensible-editor: 28: /usr/bin/sensible-editor: nano: not found
/usr/bin/sensible-editor: 31: /usr/bin/sensible-editor: nano-tiny: not found
crontab: installing new crontab

fallback?でvimに切り替わるので実害はないのですが気持ち悪い．
警告を出している sensible-editor を確認．
