我有个问题。我注意到我的 VPS 说：
=> /boot 正在使用 193MB 的 98.4%
看起来好像出了什么问题，不是吗？
我试着跑过去dpkg -l | grep linux看看那里有什么。
这是输出：

我可以做什么来解决这个问题？
我可以安全地删除什么？
答案1
您应该卸载旧版本。通常，除了您现在正在运行的版本之外，无需保留多个版本（工作版本）。
确保首先检查（使用uname）您是否在上次更新（对于最后一个版本 3.2.0-56，即今天）后实际重新启动并运行最新版本。如果您确实删除了所有内容但不包括 3.2.0.55。
如果您运行的是旧版本，则应该能够删除除正在运行的版本和最后一个版本 (3.2.0.56) 之外的所有版本，其他版本将永远不会在重新启动时启动，除非您手动执行此操作。为了进行备份，您可以保留当前的工作内核。
