I’ve received the following exception when trying to install the S3 plugin on one of the new nodes. I was able to install it on my older nodes and don’t recall running into this problem before. - OS: Ubuntu 18.04 LTS - JRE: openjdk-11-jre-headless - ES: 6.2.2 ```auto sudo bin/elasticsearch-plugin install repository-s3 Exception in thread "main" javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty at java.base/sun.security.ssl.Alerts.getSSLException(Alerts.java:214) at java.base/sun.security.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1974) at java.base/sun.security.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1926) at java.base/sun.security.ssl.SSLSocketImpl.handleException(SSLSocketImpl.java:1909) at java.base/sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1436) at java.base/sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1413) at java.base/sun.net.www.protocol.https.HttpsClient.afterConnect(HttpsClient.java:567) at java.base/sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:185) at java.base/sun.net.www.protocol.https.HttpsURLConnectionImpl.connect(HttpsURLConnectionImpl.java:163) at org.elasticsearch.plugins.InstallPluginCommand.urlExists(InstallPluginCommand.java:306) at org.elasticsearch.plugins.InstallPluginCommand.getElasticUrl(InstallPluginCommand.java:273) at org.elasticsearch.plugins.InstallPluginCommand.download(InstallPluginCommand.java:229) at org.elasticsearch.plugins.InstallPluginCommand.execute(InstallPluginCommand.java:221) at org.elasticsearch.plugins.InstallPluginCommand.execute(InstallPluginCommand.java:212) at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:86) at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) at org.elasticsearch.cli.MultiCommand.execute(MultiCommand.java:75) at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) at org.elasticsearch.cli.Command.main(Command.java:90) at org.elasticsearch.plugins.PluginCli.main(PluginCli.java:48) Caused by: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty at java.base/sun.security.validator.PKIXValidator.(PKIXValidator.java:89) at java.base/sun.security.validator.Validator.getInstance(Validator.java:181) at java.base/sun.security.ssl.X509TrustManagerImpl.getValidator(X509TrustManagerImpl.java:330) at java.base/sun.security.ssl.X509TrustManagerImpl.checkTrustedInit(X509TrustManagerImpl.java:180) at java.base/sun.security.ssl.X509TrustManagerImpl.checkTrusted(X509TrustManagerImpl.java:192) at java.base/sun.security.ssl.X509TrustManagerImpl.checkServerTrusted(X509TrustManagerImpl.java:133) at java.base/sun.security.ssl.ClientHandshaker.checkServerCerts(ClientHandshaker.java:1947) at java.base/sun.security.ssl.ClientHandshaker.serverCertificate(ClientHandshaker.java:1777) at java.base/sun.security.ssl.ClientHandshaker.processMessage(ClientHandshaker.java:264) at java.base/sun.security.ssl.Handshaker.processLoop(Handshaker.java:1098) at java.base/sun.security.ssl.Handshaker.processRecord(Handshaker.java:1026) at java.base/sun.security.ssl.SSLSocketImpl.processInputRecord(SSLSocketImpl.java:1137) at java.base/sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:1074) at java.base/sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:973) at java.base/sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1402) at java.base/sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1429) ... 15 more Caused by: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty at java.base/java.security.cert.PKIXParameters.setTrustAnchors(PKIXParameters.java:200) at java.base/java.security.cert.PKIXParameters.(PKIXParameters.java:120) at java.base/java.security.cert.PKIXBuilderParameters.(PKIXBuilderParameters.java:104) at java.base/sun.security.validator.PKIXValidator.(PKIXValidator.java:86) ... 30 more ``` ---

This sounds like a broken java installation. I recommend you try purging the java package completely and reinstalling. ---

I just tried to install it on the second node that I have added today, and it gives the same error. Which JRE do you recommend that I install? ---

Just tried ```auto sudo apt-get install default-jre ``` and tried installing the plugin again and am getting the same error. Are you suggesting that I first run: ```auto sudo apt-get purge openjdk-\* ``` and then reinstall? ---

Ok fixed. purged that JRE and installed Oracle JDK 10 and it is working fine now — thanks! ```auto sudo add-apt-repository ppa:linuxuprising/java sudo apt update sudo apt install oracle-java10-installer ``` ---
