Elasticsearch not starting, with no errors in the logs

Elastic Stack Elasticsearch
1

I've updated debian to buster version without no problem and today I've tried to update ES to 8.5 version.
Bad idea (some Java problem) so I've reinstalled previous version (6.x) but ES still not starting.

Did you look at the logs yourself? This is in the logs you shared and outlines the issue quite clearly IMHO.

the problem was the symlink :roll_eyes:
fixed with

rm elasticsearch.yml && mv elasticsearch.yml.archimed elasticsearch.yml

sorry
