だから私は同じ問題を抱えていました。これが私がそれを解決した方法です：
関連：「ターミナルで実行、表示、キャンセル、実行」というプロンプトなしでPythonスクリプトを実行するにはどうすればよいですか？フォントを一時フォルダに移動する
sudo mv /etc/fonts/ /etc/fonts.bak
デスクトップをリセットします：
dconf reset -f /
共有フォルダ内の既存のフォントの権限をリセットします：
/ usr / share / fonts -type f -exec sudo chmod 644{};
を検索します
ユーザーフォルダ内の既存のフォントの権限をリセットします：
〜/ .fonts -type f -exec sudo chmod 644{};
を検索します
フォントを元のフォルダに戻します：
sudo mv /etc/fonts.bak/ / etc / fonts
フォントキャッシュをリセット
sudo fc-cache -r -v
欠点は、デスクトップをリセットすることにより、そこで行ったカスタマイズを最初からやり直す必要があることです。また、私は決して専門家ではありませんが、上記のことがうまくいったので、共有しようと思いました。
