Dear Elastic Team,
I have installed X-Pack 5.5.1 on SUSE Linux Enterprise Server 12 SP2 using the following commands:
cd /tmp/elastic-depot
wget [https://artifacts.elastic.co/downloads/packs/x-pack/x-pack-5.5.1.zip](https://artifacts.elastic.co/downloads/packs/x-pack/x-pack-5.5.1.zip)
/usr/share/elasticsearch/bin/elasticsearch-plugin install file:///tmp/elastic-depot/x-pack-5.5.1.zip
The following commands were added for testing at the end of /etc/elasticsearch/elasticsearch.yml file:
xpack.security.enabled: false
xpack.monitoring.enabled: true
xpack.graph.enabled: false
xpack.watcher.enabled: false
After the service was restarted the following error message was logged:
Caused by: java.lang.IllegalArgumentException: none of the ciphers [TLS\_ECDHE\_RSA\_WITH\_AES\_128\_CBC\_SHA256,
TLS\_ECDHE\_ECDSA\_WITH\_AES\_128\_CBC\_SHA256, TLS\_ECDHE\_ECDSA\_WITH\_AES\_128\_CBC\_SHA, TLS\_ECDHE\_RSA\_WITH\_AES\_128\_CBC\_SHA,
TLS\_RSA\_WITH\_AES\_128\_CBC\_SHA256, TLS\_RSA\_WITH\_AES\_128\_CBC\_SHA] are supported by this JVM

Hey,
you are running an unsupported JVM version, see [https://www.elastic.co/support/matrix#show\_jvm](https://www.elastic.co/support/matrix#show_jvm)
Either use openjdk, oracle JVM or Azul.
