I stopped ES service, then used: sudo yum remove elasticsearch To get it out of here. I changed repos files to use 6.x versions. Then i tried installing it with sudo yum install elasticsearch-6.7.2 But i get this error: > could not find java; set JAVA\_HOME > error: %pre(elasticsearch-0:6.7.2-1.noarch) scriptlet failed, exit status 1 > Error in PREIN scriptlet in rpm package elasticsearch-6.7.2-1.noarch > Verifying : elasticsearch-6.7.2-1.noarch 1/1 > > Failed: > elasticsearch.noarch 0:6.7.2-1 ---
