Is Elasticsearch 1.5.2 is not supported on UBUNTU 20.4? How to resolve this? Please help.

@kiranoza, it looks like the elasticsearch 1.5.2 package wasn’t installed properly in one of the previous tasks. I checked an Open edX instance VM running Koa.3 on Ubuntu 20.04 and can see that elasticsearch 1.5.2 is installed properly, and the service is running without any issues. There is no file named systemd-entrypoint under /usr/share/elasticsearch/bin and the systemd startup command doesn’t invoke that script at all.

Here is the confirmation that version 1.5.2 is indeed installed.

$ apt show elasticsearch

  - Support for more than one index.
  - Support for more than one type per index.
  - Index level configuration (number of shards, index storage, ...).
 + Various set of APIs
  - HTTP RESTful API
  - Native Java API.
  - All APIs perform automatic node operation rerouting.
 + Document oriented
  - No need for upfront schema definition.
  - Schema can be defined per type for customization of the indexing process.
 + Reliable, Asynchronous Write Behind for long term persistency.
 + (Near) Real Time Search.
 + Built on top of Lucene
  - Each shard is a fully functional Lucene index
  - All the power of Lucene easily exposed through simple
    configuration/plugins.
 + Per operation consistency
  - Single document level operations are atomic, consistent, isolated and
    durable.

and here is the systemd unit file for the service.

Can you check and verify whether elasticsearch=1.5.2 is installed properly and also check the contents of the systemd unit file?
