我昨天運行 apt-get Upgrade 來更新我的核心（ubuntu 15.04），並且 /boot 內存不足（通常如果沒有足夠的空間，它會阻止升級任務運行）
我不小心刪除了活動內核，導致我在此處執行以下步驟 -意外刪除所有核心後如何恢復系統？
我被困在第 13 步，因為之前的記憶體錯誤阻止我安裝當前核心或升級其餘核心。
升級拋出以下錯誤

由於同樣的錯誤，我也嘗試過清除並安裝新的，沒有骰子

我認為這值得提出自己的問題，因為這是一個 dpkg 問題，而不是與上述問題直接相關的問題
答案1
不確定還能做什麼，我只是刪除了包裹
sudo apt-get remove linux-image-extra-3.19.0-31-generic
並重新安裝它
apt-get -y upgrade linux-image-generic
似乎已經成功了
