我们继承了一台 Ubuntu Linux 服务器，该服务器的 /boot 分区空间不断不足，现在 clean 和 autoclean 命令不再起作用。我们怀疑问题与从未删除旧内核有关。我们不是 Linux 专家，因此不太愿意运行可能导致该服务器无法启动的命令。运行该uname -r命令时，版本为 3.13.0-53-generic。
运行命令后dpkg -l | grep linux-image-结果如下：

因为这里有太多没有意义的东西，我不确定如何使用sudo apt-get autoremove <old kernel>正确的语法运行命令以确保保留当前和最近的前一个命令。
任何见解或帮助都将不胜感激。
答案1
因为你知道命令uname -r和dpkg -l | grep linux-image-，所以你比我更了解 Linux :)
我以前用这样的命令清理过旧内核：
rm /boot/*-2.6.*，，，等等。然后也许你也可以运行，但这并不重要。rm /boot/*-3.2.*rm /boot/*-3.13.0-37-*update-grub
到目前为止我还没有遇到什么不好的事情（也许我只是运气好）。
