RVM 在 apt-get update 出现错误时表现不佳.如果您的 apt sources 有一个无效的存储库，导致 404 或 GPG 错误，RVM 将拒绝工作.这可能会令人困惑，因为即使错误的存储库与 ruby 或 RVM 无关，也会发生这种情况.

RVM doesn't behave well if apt-get update has errors. If your apt sources have an invalid repository that gives 404 or GPG error, RVM will refuse to work. This can be confusing because it happens even if the faulty repository has nothing to do with ruby or RVM.

以下修复对我有用(Ubuntu):

The following fix worked for me (Ubuntu):

运行 apt-get update 看看有没有错误.编辑 /etc/apt 中的 sources.list 和 precise.list 以删除有问题的存储库.重复直到 apt-get update 成功且没有任何错误.然后尝试运行 RVM.

Run apt-get update and see if there are any errors. Edit your sources.list and precise.list in /etc/apt to remove the faulty repositories. Repeat until apt-get update succeeds without any errors. Then try running RVM.
