我犯了一個可怕的錯誤並刪除了 gtk（以及所有連結的資料包，包括 gnome）。之後，我已經恢復了我的 GUI 和
sudo apt-get install ubuntu-desktop大部分關鍵資料包，但現在當我嘗試執行以下操作時出現錯誤sudo apt-get update：

E: Some index files failed to download, they have been ignored, or old ones used instead.
我已經發布了sudo apt-get clean all，它沒有改變任何東西。
/etc/apt/sources.list好像：
deb http://ru.archive.ubuntu.com/ubuntu/ maverick main contrib restricted
deb-src http://ru.archive.ubuntu.com/ubuntu/ maverick main contrib restricted
deb http://repo.yandex.ru/ubuntu/ maverick main non-free
sudo apt-get updatecontrib沒有deb 記錄就可以正常運作
有什麼辦法可以解決這個問題嗎？
我使用的是ubuntu 10.10。
答案1
contrib不是官方 ubuntu 鏡像的有效部分，因此contrib/source/Sources無法找到神秘訊息。
repo.yandex.ru不是官方列出的https://launchpad.net/ubuntu/+archivemirrors。該鏡像的部分non-free不包含任何二進位檔案或原始程式碼。如果您想使用 Yandex 鏡像，請使用mirror.yandex.ru。
此外，您的儲存庫來源清單遺失，security.ubuntu.com這可能會導致安全更新延遲。
您應該將存儲庫來源至少設定為：
deb http://ru.archive.com/ubuntu/ maverick main restricted
deb-src http://ru.archive.com/ubuntu/ maverick main restricted
deb http://security.ubuntu.com/ubuntu/ maverick main-security restricted
deb-src http://security.ubuntu.com/ubuntu/ maverick main-security restricted
此列表中您丟失了很多軟體包，我建議您使用新安裝時提供的列表，將以下文字儲存為/etc/apt/sources.list：
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
