從失敗的更新中恢復

強文本我已經運行 18.04.02 Desktop 的穩定安裝大約 30 個月了。該伺服器大約兩週沒有開機，因此今天早上開機時，它進行了自動安全更新。他們完成後，我運行更新管理器並收到這些錯誤訊息

顯然這些包不一致。我透過執行「sudo nano /etc/apt /sources.list」來檢查我沒有任何第三方儲存庫。至少我是這麼認為的。

無論如何我可以恢復到一組一致的軟體包嗎？不，我沒有最近的備份。我當然遵循了錯誤訊息中的建議

機器看起來很穩定，但現在無法更新。這是一個無望的原因嗎？

謝謝你的幫助

答案1

您的輸出包含解決問題所需的資訊：

cannot copy extracted data for './usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37.53.5' to '/usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37.53.5.dpkg-new':unexpected end of file or stream

讓我們抽像一下以便更容易理解...

cannot copy extracted data for X to Y:unexpected end of file or stream

X = './usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37.53.5'
Y = '/usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37.53.5.dpkg-new'

這是什麼意思？

」文件或串流意外結束」 的意思正如其所言 - 軟體包不完整或損壞。您必須將其從本地快取中刪除，然後讓 apt 下載該軟體包的新的、全新的、完整的副本。

哪個包？

讓我們使用 X 提供的路徑來問這個問題：

  • 包名在第二行：libwebkit2gtk-4.0-37
$ dpkg -S /usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37
libwebkit2gtk-4.0-37:amd64: /usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37

如何刪除損壞的本機軟體包並下載全新的副本？

$ sudo apt clean libwebkit2gtk-4.0-37                 // Delete local
$ sudo apt update
$ sudo apt install --reinstall libwebkit2gtk-4.0-37   // Download fresh

答案2

對我有用的解決方案是執行 sudo apt full-upgrade ，其效果是下載損壞的軟體包的新副本，然後執行 sudo apt update
