答え1
正しいリポジトリは次のとおりです。
deb http://www.geogebra.net/linux/ stable main
問題を解決するにはsources.list
:
sudo sed -i '/geogebra/d' /etc/apt/sources.list
geogebra
リポジトリをきれいに追加します。
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C072A32983A736CF
sudo add-apt-repository "deb http://www.geogebra.net/linux/ stable main"
sudo apt update
答え2
テキスト画像を投稿してはいけないという意見と、アカウントのマージを提案する意見に同意します。
これは非常に単純な問題であり、エラーメッセージはデフォルトでエラーがどこにあるかを示しています(行58)sources.list
。
deb http://www.geogebra.net/linux/stable main
まだgeogebraをインストールしようとしていないので、正しい行をどのように表示するのかわかりませんが、私の考えでは、最後の行(および間/
の行など)を空白に置き換える必要があるようです。linux
stable
私は60行目に同じ問題がありますsources.list
。私の本能はその行を削除することです(しかし私が言ったように、私はgegebraをインストールしようとしませんでした)。
