ruby-on-rails - Ruby および Rails のアップグレード中に Bundler に依存関係エラーが表示される

Question

ここで私を助けてください。ルビーとレールをアップグレードしていましたが、依存する宝石もアップグレードが必要です。

以前は ruby​​ のバージョンが 2.3.0 で rails が 4.2.x でしたが、現在は 2.6.0 にアップグレードされ、rails は 6.0.4 にアップグレードされています。

以下のエラーが表示された場合、actionpack は 6.0.4 に解決され、public_activity にも actionpack >=3.0.0 が必要です。これは、6.0.4 が許容され、バージョン = 6.0.4 を使用して明らかにレールを使用する必要があることを意味します。何人かの専門家がそれにいくらかの知識を投げかけることができますか。
