sudo apt-get アップデートは利用できません。

私はDebian 11を使用していますが、今回はコマンドに多くの問題がありますが、最も奇妙なことはもう更新できないということです。すると、次のような結果が表示されます。

E: The repository 'http://archive.ubuntu.com/ubuntu wily Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch https://sourceforge.net/projects/madlinux/files/repo/dists/core/InRelease  Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)
E: The repository 'https://sourceforge.net/projects/madlinux/files/repo core InRelease' is no longer signed.

更新しないと何もできないので、誰かが私を助ける方法を知っていることを願っています。よろしくお願いします！
