所以我的 Ubuntu VM /boot 現在已經滿了，我知道我很久以前就設法解決了這個問題，但現在我所做的一切似乎都行不通。

xxx@ubuntu:~$ df -h

我正在執行 GNU/Linux 4.4.0-145-generic x86_64，如果我執行：

dpkg --list | grep linux-image

我得到了很多核心映像。所以因為它已滿，我想嘗試刪除：

sudo apt autoremove

和：

sudo apt-get purge linux-image-4.4.0-101-generic

我得到：

Läser paketlistor… Färdig

Du bör köra ”apt-get -f install” för att korrigera dessa.
Följande paket har beroenden som inte kan tillfredsställas:
linux-image-generic : Beroende av: linux-image-4.4.0-150-generic men det är inte installerat eller
                                   linux-image-unsigned-4.4.0-150-generic men det är inte installerat

是的，我知道這是瑞典語，但它說它依賴於 linux-image-4.4.0-150-generic，但它沒有安裝。所以它建議我執行：

apt-get -f install

然後它嘗試下載 linux-image-4.4.0-150-generic 但由於空間不足當然會失敗。我確信我找到了一些方法來實際使用 rm 命令手動刪除核心映像，但我不知道它們的核心映像儲存在哪裡，我也嘗試安裝 byobu，以幫助我刪除核心映像但沒有空間……你知道..

那麼，我現在的解決方案是手動刪除核心映像嗎？如果如何？

謝謝！

xxx@ubuntu:/boot$ sudo du /boot

7121    /boot/grub
12      /boot/lost+found
477697  /boot

是的，我在 /boot 文件夾中找到了核心。

手動清理/boot

進入/boot目錄：

cd /boot

獲取所有文件的列表：

ls

獲取目前執行的核心版本：

uname -r

刪除舊核心和 initramdisk。保留目前執行的核心及其 initrd。

rm FILE_NAME FILE_NAME FILE_NAME
# Maybe you should use `sudo`:
sudo rm FILE_NAME FILE_NAME FILE_NAME

（只需複制和粘貼文件名）

正確的清理方法

Install aptitude，它是基於菜單的包管理器：

sudo apt-get install aptitude

執行能力：

sudo aptitude

查找（鍵/）文本linux-image，按Enter。對於要刪除的每個包，按_(purge) 或(remove)。-按g查看更改，然後再按g一次。
