Good morning,
The first sorry for my English. I am new on Linux, I have to install Kibana. I'm using Ubuntu Server 2004.
I installed kibana 7.9.3 from the .tar file following the instructions https://www.elastic.co/guide/en/kibana/7.x/targz.html
When executing kibana I get all these logs with many errors and warnings:

I looked in the forums but, they haven't helped me, I'm new to Linux and, there are many things that I still do not know how to run and, I do not have enough knowledge.
