我正在運行 13.10。我刪除了 emacs，然後運行 sudo apt-get autoremove，但它決定需要刪除所有這些其他東西（其中很多我可能需要）。以下是完整列表：

Use 'apt-get autoremove' to remove them.
我再次嘗試安裝和刪除 emacs，但它仍然堅持要我刪除所有這些。 libreoffice 和 python-twisted 曾經在這裡，直到我將它們設定為手動安裝。為什麼 Ubuntu 要刪除所有這些？
答案1
您認為需要的任何軟體包只需執行以下操作：
sudo apt-get install package-you-need
這樣您就可以將軟體包標記為手動，然後就可以執行自動刪除。
答案2
不用擔心，你不需要它們
sudo apt-get autoremove
Autoremove 用於刪除為了滿足某些套件的依賴關係而自動安裝但不再需要的套件
