编辑：只需将旧内核文件暂时移动到临时文件夹，即可创建少量空间并让命令再次工作。
答案1
cd /boot
在目录中找到最旧的内核/boot：
sudo dpkg --force-all -P Full_name_of_oldest_kernel
sudo apt autoremove --purge
有多种方法可以自动执行上述命令以实现可持续性。cron job例如。
答案2
我成功了：
- 创建一个临时文件夹（例如 /home/user/temp）
- 运行 uname -r 来确定哪个内核正在运行，不要触碰它！
- 将特定未使用的内核的内核文件移动到此临时文件夹。
您将获得一些空间，并且命令应该可以再次工作。来源：http://natesbox.com/blog/ubuntu-unable-to-installupdate-packages-full-boot-partition/
附言：我忘记为该服务器设置自动删除以进行自动更新。我认为这可能是导致问题的原因。
