今日、Canonicalのパートナーと独立したリポジトリが「ソフトウェアとアップデート」の「その他のソフトウェア」タブから欠落していることに気付いたとき、奇妙な問題に遭遇しました。また、「main」、「universe」、「multiverse」、「restricted」がすべて無効になり、「trusy-security」、「trusty-updates」、「trusy-proposed」、「trusty-backports」も無効になっていることに気付きました。
問題は、Canonicalリポジトリと独立したリポジトリを再度追加して、それらを再度有効にするにはどうすればよいですか?そして、何がこれを引き起こしたのでしょうか?
前もって感謝します。
