aptが破損しています。インストール候補がなく、アップデートにリリースファイルがありません。

私のアパートとパッケージマネージャは完全に破損しています。

誤った情報：

Package 'package' has no installation candidate

Cannot initiate the connection to deb.debian.org:80 (2a04:4e42:62::644). - connect (101: Network is unreachable)

stable InRelease' does not seem to provide it (sources.list entry misspelt?)

Updating from such a repository can't be done securely, and is therefore disabled by default.

etc.
