无法从完全启动磁盘中删除旧内核
我无法在我的机器上安装或更新任何软件。
使用我令人难以置信的推断能力，我推断出/ boot已经满了并引起了我的全部心痛。

我确定这必须是一个重复的问题，但在搜索类似问题的解决方案后，并没有缓解我的困境。
最后，我是RHEL管理员，请原谅我的无知 – 我们的BIND服务器必须在Ubuntu上作为我们姐妹公司的一些免费colo空间的条件。 我做错了什么导致了这个问题，我怎么能避免它在将来发生呢？
当我在这个网站上尝试类似的解决方案，比如如何在/ boot中释放更多空间？ 我明白了：

谢谢@mikewhatever，
sudo dpkg --force-all -P pkgname就是答案
所以： sudo dpkg --force-all -P linux-image-extra-3.19.0-26-generic为我做了
从Ubuntu 14.04 Trusty开始，此命令支持除最后两个之外的旧内核。 通过在终端输入命令来删除除最后2个之外的旧内核非常容易和安全：
sudo apt-get autoremove --purge
