なにから何に上げてるのかがないと。、、。、
Railsのバージョンアップ中です
rails sで起動後、localhost:3000にアクセスすると以下エラーが出ます

引数の数が想定と異なる、というエラーなのはわかるのですが、バージョンアップ前には動いていたコードなので自分で書いたコードについては問題ないはずです。
どのあたりに目星をつければよいのでしょうか？

４から直６ですか、Railsの推奨では
４の最終versionにあげ
５に上げ
６に上げる
という手順です。
まぁ、私も面倒だから ２から４へ直に、４から６へ直に上げましたが、それは
Rails のversionを上げていく
というよりは
Railsの新しいアプリを元のcodeを利用して作る、
という覚悟でした。
codeもまず動かなくなります。belongs_to では必ず引っかかるかと。他に何が有ったか覚えてませんが、障害が出る毎にコツコツなおしました。
それと ４と６では assets周りが変わっているのでそのままでは起動もしないかも。
node の設定とかもありますので、
Rails6でのassets、app/javascript あたりの設定を調査して仕切り直すのがよいかも。
