海因内玛:
我尝试将您请求的项目添加到我的原始帖子中，但超出了允许的总字符数（30000）。
因此，我删除了原始输出dpkg -l 'linux-*'
我还将输出：添加ls -al /
到您的所需项目列表中。
希望我正确插入了屏幕截图。
tscale:~$ ls -al /boot

它不仅显示标记为 的实际安装的内核ii，还显示过去安装的内核或软件包，即使它们现在已被删除。很可能您已在未使用 的情况下删除了它们purge。
如果您尝试通过 卸载 Linux 内核sudo apt purge linux-image-5.3.0-18-generic，您可能会得到以下结果：
Purging configuration files for linux-image-5.3.0-18-generic (5.3.0-18.19+1) ...
rmdir: failed to remove '/lib/modules/5.3.0-18-generic': Directory not empty
此内核从 grub 中消失，并已从/boot文件夹中删除，但仍保留在/lib/modules/
$ sudo apt purge linux-image-5.3.0-18-generic linux-headers-5.3.0-18

Package 'linux-image-5.3.0-18-generic' is not installed, so not removed
The following package was automatically installed and is no longer required:

Removing linux-headers-5.3.0-18 (5.3.0-18.19) ...
在此之后，当我运行时，linux-headers-5.3.0-18和linux-image-5.3.0-18-generic不再列出dpkg -l linux-* | grep ii，但是我之前已删除它们，但没有purge选择。
如果要清除特定版本，请使用：
sudo apt purge linux-*5.3.0-18*
