Linux Debianは破損したパッケージの依存関係の問題を検出できません。

私はアップグレード（sudo apt upgrade）を試みましたが、エラーのため失敗しましたE: Broken Packages。dpkg -l | grep brokenそれをしてdpkg -l | grep held何も返さなかった。私のsources.list外観は次のとおりです。

sudo apt install -f私もこの方法をしましたが、sudo apt update && sudo apt upgrade -f && sudo apt dist-upgrade -f問題は解決されませんでした。また、代わりにaptitudeandを使ってみました。これはいくつかのパッケージバージョンの競合に関するものだと思いますが、まだ解決策がわかりません。synapticapt
