當我嘗試升級到Flash的最新版本，我收到錯誤消息的Ubuntu 16.05閃存升級從Version11.2.202.635到23.0.0.162
W:The repository 'http://ppa.launchpad.net/pidgin-developers/ppa/ubuntu xenial Release' does not have a Release file.,
W:Data from such a repository can't be authenticated and is therefore potentially dangerous to use.,

E:Failed to fetch http://ppa.launchpad.net/pidgin-developers/ppa/ubuntu/dists/xenial/main/binary-amd64/Packages 404 Not Found,
E:Some index files failed to download. They have been ignored, or old ones used instead.
我不知道如何解決這個。
我試圖通過Adobe Flash Player Download進行升級。我一直在選擇「APT For Ubuntu 10.04+」
我不知道我需要提供哪些其他信息來解決這個問題。請指教。
