作为开发人员，我需要安装几个应用程序。但从未想过它会需要超过 15GB 的空间。我不断收到磁盘空间不足的警告，尝试了这里介绍的几种方法根驱动器的磁盘空间不足。如何释放空间？ 我现在应该怎么做？
df-h给我这个

uname -r
5.4.0-37-generic
dpkg --list | grep linux-image给我吗：
ii linux-image-5.4.0-37-generic 5.4.0-37.41 amd64 Signed kernel image generic
ii linux-image-generic 5.4.0.37.40 amd64 Generic Linux kernel image
ii linux-image-unsigned-5.4.0-33-generic 5.4.0-33.37 amd64 Linux kernel image for version 5.4.0 on 64 bit x86 SMP
我听了一些指南声称/最多只需要 15gb。现在我搞乱了。我的/home文件还有很多空间。
答案1
或许http://manpages.ubuntu.com/manpages/focal/man1/purge-old-kernels.1.html可以帮助您清理旧的内核模块并释放根文件系统上的磁盘空间。
但如果驱动器上有更多可用磁盘空间，请尝试扩大分区如何扩展我的根（/）分区？。也许您可以挤压其他分区。
