Plugins Manager error

Hi,

We just enabled firewall access from our Gerrit 3.1.8 server (VM) in order to retrieve plugin details from https://gerrit-ci.gerritforge.com/.

Note that we are using a self signed SSL certificate for Gerrit.

After restarting Gerrit, we encounter the below error. Not sure whether my hunch is correct that since the gerritforge site's certificate is private, we need to trust it.

Please advise how to do so if this is the case.

Have you checked if your JVM has the SSL Root CA Certificates?

You can also check with OpenSSL:

$ openssl s_client -host gerrit-ci.gerritforge.com -port 443

The certificate chain is:

Certificate chain

0 s:/CN=*.gerritforge.com

i:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=GeoTrust RSA CA 2018

1 s:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=GeoTrust RSA CA 2018

i:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert Global Root CA

2 s:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert Global Root CA

i:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert Global Root CA

However, if you have an old Java JVM, it is possible that your truststore doesn’t contain the root CA certificate.

HTH

Luca.

Adrien

Hi Luca,

Thanks for the response.

Actually, we are using a more recent OpenJDK version as shown below which is built-in on RHEL8. We actually moved away from manually installed Java so that OS patching will take care of the Java upgrade and we don't have to worry for security vulnerabilities:

OpenJDK Runtime Environment 18.9 (build 11.0.10+9-LTS)

OpenJDK 64-Bit Server VM 18.9 (build 11.0.10+9-LTS, mixed mode, sharing)

I tried to run openssl and has observed the below (I just omitted the server certificate section BEGIN/END):

openssl s_client -host gerrit-ci.gerritforge.com -port 443

CONNECTED(00000003)

depth=2 C = US, O = DigiCert Inc, OU = www.digicert.com, CN = DigiCert Global Root CA

Hi All,

Just an update. After opening the firewall and ensuring that gerritforge's root ca is in the jvm truststore, the ERROR message went away.

However, it was replaced by a WARN message which seems to refer to the current Gerrit version (3.1.8) that we are using.

Is there anyone here who can enlighten what is the meaning of "No plugins available for Gerrit version 3.1.8" and what can be the best way to move forward.

It seems like we can just ignore this warning since it's not stopping Gerrit anyway.

Hope to hear from anyone soon.

Yeah, the error was:

"Verify return code: 19 (self signed certificate in certificate chain)”

That means that the CA root certificate was not present in the system trust-store.

However, it was replaced by a WARN message which seems to refer to the current Gerrit version (3.1.8) that we are using.

Yeah, Gerrit v3.1 is EOL and therefore the associated builds aren’t available on the Gerrit-CI anymore.

Glad you managed to fix the issue.

Luca.
