curl: (60) SSL certificate problem: Invalid certificate chain
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of /Users/iju/.gvm/archives/groovy-2.4.3.zip or
        /Users/iju/.gvm/archives/groovy-2.4.3.zip.zip, and cannot find /Users/iju/.gvm/archives/groovy-2.4.3.zip.ZIP, period.

Stop! The archive was corrupt and has been removed! Please try installing again.

3.対応したこと

https://github.com/gvmtool/gvm-cli/issues/327
にある通り、
echo insecure >> ~/.curlrc
をしてverificationをoffし、再度
gvm install groovy
しただけ。

まとめ

他にもあるっぽいけど、特に問題なければcurlのverificationをoffにするだけでよいっぽい。
