无法在Ubuntu 18.04.3 LTS上安装python3.6-venv

Question

我在运行Ubuntu 18.04.3 LTS的计算机上内置了python3。 我无法安装python3.6-venv。它显示以下错误：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package python3.6-venv is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'python3.6-venv' has no installation candidate

正如其他一些SO职位所建议的，我也运行了apt-get update，但问题仍然存在。请告知。

Answer 1

apt-get update为我解决了这个问题
