我的根分区几乎没有空间了，当我检查原因时，我意识到我安装了多个 linux-modules-extra 包，它们都很重，并且带有旧的内核版本。
当我跑步时
dpkg-query -W --showformat='${Installed-Size;10}\t${Package}\n' | sort -k1,1n
对于最后几个包，我得到了以下输出：
168006 linux-modules-extra-5.0.0-37-generic

我的问题是，我可以删除所有的 linux-modules-extra 包吗？
答案1
不是，因为大多数软件包都已经被卸载了。
“安装尺寸“表示安装包后占用的空间大小。任何包一次只能安装一个版本。所有其他包都已被卸载，并由较新的版本替换。
让我们看一下，使用 dpkg 列出该包的所有已知版本：
- 查看第一列：
ii表示“已安装”，rc表示“已卸载”
