如何切换或修复Ubuntu19.04的ppa配置和源？

Question

我刚在宏碁Nitro 5笔记本电脑上安装了Ubuntu19.04。

我很难按照gorails.com上的说明在rails上安装ruby和ruby

运行以下命令时：

$ curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -

我得到以下错误：

## Installing the NodeSource Node.js 8.x LTS Carbon repo...

我到处找遍了，一直找不到解决办法。

Answer 1

您为您的Ubuntu发行版添加了do 没有文件的PPA (19.04或Dingo)。

因此，您需要从系统中删除它：

sudo add-apt-repository -r ppa:paulo-miguel-dias/pkppa

然后继续跟随你的指引。
