安装nodejs及heroku存在的问题

Question

我正在尝试从https://nodejs.org/en/download/package-manager/安装节点js。

安装curl和python-software-properties后，以下命令有问题：

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -

我有这样的输出：

...

Err:8 https://cli-assets.heroku.com/branches/stabile/apt ./ Packages
  404  Not Found

...

W: The repository 'https://cli-assets.heroku.com/branches/stabile/apt ./ Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch https://cli-assets.heroku.com/branches/stabile/apt/./Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
Error executing command, exiting

我怎么才能修好它？

Answer 1

你可以去System Settings->Software & Updates。然后选择Ubuntu Software选项卡并取消选中链接项如下：

http://ppa.launchpad.net/fossfreedom/packagefixes/ubuntu xenial Release
http://ppa.launchpad.net/thefanclub/grive-tools/ubuntu xenial Release
http://ppa.launchpad.net/boomaga/ppa/ubuntu xenial InRelease
http://ppa.launchpad.net/ubuntu-audio-dev/ppa/ubuntu xenial Release
http://ppa.launchpad.net/me-davidsansome/clementine-dev/ubuntu xenial InRelease

打开它之后，运行sudo apt update，就可以更新您的系统了。
