如果有两个软件包,如何从“apt-cache show”输出中找出软件包版本?

如果有两个软件包,如何从“apt-cache show”输出中找出软件包版本?

我从未见过apt-cache show [exact package name]显示两个包信息块(之后sudo apt-get clean):

我应该参考哪个块才能弄清楚我正在使用哪个版本?

我正在使用 Ubuntu 17.04。

答案1

如果您想知道您正在使用哪个版本,请使用其他工具:

dpkg -l nvidia-367

或者 :

apt-cache policy nvidia-367

apt-cache当存储库中有两个版本的软件可用时,就会发生这种情况。

您也可以使用apt show而不是apt-cache来获取最新版本的信息。

或者也指定版本:

apt-cache show package-name=1.17.1-1ubuntu1.1
