可以有两个版本：

版本：1.187.10

版本：1.187

我可以删除一个吗？例如 1.187 ?

Answer 1

您正在显示apt-cache show linux-firmware- 此命令显示可用版本的输出。

只有一个是真正安装的。
您可以通过以下方式检查其版本号：

• apt-cache policy linux-firmware
• dpkg -l linux-firmware

或者出于同样的目的使用在 packages.ubuntu.com上的搜索。
对于 Ubuntu 20.04 LTS（焦点），最新版本是1.187.10，来自焦点更新口袋。

不需要额外的操作。APT 已经为您完成了所有工作。
