解决方案

GPG

We use GPG for signing. Both gpg and gpg2 should be fine.

Sometimes gpg has problems downloading keys from remote server, it might >be better to work with gpg2 if it's available for your system. However it has >been reported that gpg2 in version 2.1.17 is also affected by such issue. We >recommend you to downgrade or upgrade it to a newer version.

####### ∞Install our keys

Make sure to only trust the keys of people you trust - if you trust to run our code - trust our keys. Here are the keys from our maintainers:

409B6B1796C275462A1703113804BB82D39DC0E3 # mpapis
7D2BAF1CF37B13E2069D6956105BD0E739499BDB # pkuczynski

As a first step, before attempting RVM install, you should install gpg2 and import those keys:

gpg --keyserver hkp://pool.sks-keyservers.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

Solution: gpg: 从公钥服务器接收失败：No route to host

If you encounter problem with the key server above, try a different one. Some alternatives are presented below:

hkp://ipv4.pool.sks-keyservers.net
hkp://pgp.mit.edu
hkp://keyserver.pgp.com

######## ∞Alternatives

Alternatively you might want to import keys directly from our web server, although this is a less secure way:

curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -

Run verified installation

We usually recommend everywhere to run installation using following command:

\curl -sSL https://get.rvm.io | bash -s stable
