Failed to install google cloud sdk: "<gcloud.components.update> Failed to get component" Windows7
When I try to intall google cloud sdk the following error occurs:
ERROR: (gcloud.components.update) Failed to get component list from server. Check your network settings and try again. The Google Cloud SDK installer is now out. Press any key to continue.,.
result = func(*args) File "C:\python27_x64\lib\urllib2.py", line 1222, in https_open
return self.do_open(httplib.HTTPSConnection, req) File "C:\python27_x64\lib\urllib2.py", line 1184, in do_open
raise URLError(err) urllib2.URLError: <urlopen error [Errno 10061] No connection could be made because the target machine actively refused it>
Any ideas?

I was getting a similar error both when installing and in some commands on another previously working installation. After scrolling through and adding some logs, it looks like the SSL certificate check fails to request a list of components from google servers:
$ gcloud preview managed-instance-groups ...
You do not currently have this command group installed. Using it requires the installation of components: [preview]
Could not fetch [https://dl.google.com/dl/cloudsdk/release/components-2.json]
<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)>
ERROR: (gcloud) Failed to fetch component listing from server. Check your network settings and try again.
To fix the problem (almost certainly impractical), I disabled SSL Cert Validation for this single request. If you want to go down this path, change MakeRequest()
to
./google-cloud-sdk/lib/googlecloudsdk/core/updater/installers.py:248
from
return urllib2.urlopen(req, timeout=TIMEOUT_IN_SEC)
in
return urllib2.urlopen(req, timeout=TIMEOUT_IN_SEC, context=ssl.SSLContext(ssl.PROTOCOL_TLSv1))
(There's an issue open to https://code.google.com/p/google-cloud-sdk/issues/detail?id=143 .)
UPDATE: 26/05/15
In my case, it turned out to be a mismatch between my installed version of OpenSSL and the version of OpenSSL that Python is referring to (possibly after an upgrade to OpenSSL@1.0.2a-1
).
To solve this problem, I updated my OpenSSL version to the latest version:
brew update
brew upgrade openssl
Then I reinstalled Python, referencing this updated version of OpenSSL:
brew uninstall python
brew install python --with-brewed-openssl
After that, I got tired of installing the Google Cloud SDK (because I'm a little there to find a solution, you may not need to do this) and installed from scratch:
curl https://sdk.cloud.google.com | bash
And we are golden!

TL; DR
- Find the file
cacerts.txt
used by google scripts. Should be in<google-cloud-sdk>/lib/third_party/httplib2/cacerts.txt
. - Open
https://dl.google.com
Firefox and export its certificates. - Copy the contents of the certificate (s) to the end of the file
cacerts.txt
.
You may also need to make sure your system version of openssl is the same version as opensl which is used by python, like jemartti's answer . I tried it and it wasn't enough. I don't know if it matters.
Steps taken to achieve this solution
After trying jemartti's answer not to use, I used a flag --verbosity debug
to trace the point of failure. Output:

So I opened /usr/local/google-cloud-sdk/core/util/urlopen_with_cacerts.py
and saw that it is calling a method httplib2
urlopen
with an argument cafile
obtained from httplib2.CA_CERTS
. I added a line that prints this httplib2.CA_CERTS
, the output of which is:
/usr/local/google-cloud-sdk/lib/third_party/httplib2/cacerts.txt
Then, as described in this answer , this is why I did:
- Open the URL in Firefox and export the certificate (s).
- Copy the contents of the certificate (s) to the end of the file
cacerts.txt
.
As a Mac user, I also used the one-line file described here (which for some reason gave a different certificate than Firefox's certificate export function) to save the certificate (s) on my machine (replace exmple.com
and example.crt
as needed):
openssl x509 -in <(openssl s_client -connect example.com:443 -prexit 2>/dev/null) -out ~/example.crt
