ElasticSearch restart problem (Lucene Version mismatch)

[JUN_HO_CHOI_KR_SEL (JUN HO CHOI 최준호 KR SEL)]

Hi I using Azure Vm and Elastic & Kibana
I restart the vm and i Encounterd the error

when i restart the Elasticsearch
the error message is

Job for elasticsearch.service failed because the control process exited with error code.
See "systemctl status elasticsearch.service" and "journalctl -xe" for details.

when i find log of this

[2022-07-29T13:41:56,909][WARN ][stderr                   ] [Dev-Elasticsearch-KK

mentAwareCommand.java:75)

i think it is because of the version problem, because before the restart vm i did apt-upgrade..

how can i solve this problem. please help, I am just new to elasticsearch( only 2days)

Welcome to our community!

What was the results of the apt-upgrade?

[JUN_HO_CHOI_KR_SEL (JUN HO CHOI 최준호 KR SEL)]

Hi~
That Upgrade for the azure vm but it makes crash the version of Lucene and Elasticsearch

In this case just uninstall and install elasticsearch will help?
Is there a way not to affect the existing configuration file and data file?

[warkolm (Mark Walkom)]

It really depends on what happened with the upgrade, what the steps were to upgrade, what version you went from and to, what the outcome was.

above code is my whole upgrade progress by log

so after vm restart
i can't start elasticsearch and kibana both
and the log of elasticsearch is in the main question content

Please don't post pictures of text, logs or code. They are difficult to read, impossible to search and replicate (if it's code), and some people may not be even able to see them

i typed it all and modified above image to code!
