Kibana cannot read UUID file

Elastic Stack Kibana
1

Hi,

I'm trying to upgrade the Elastic Stack from 7.6.2 to 7.9.1 but for some reason Kibana is not starting.
The error logged during startup is:

Kibana cannot read the uuid file, please make sure server.uuid is set in kibana.yml and it has sufficient privileges for read/write.

Any idea what's going on, I tried setting path.data and the location has og+rw with ownership as kibana:kibana?

Best Regards,
Ayush

Hi @Ayush_Mathur
just to check: are you running the kibana process with the kibana user?
if so, please check the permission for the kibana user on that directory and the uuid file in that directory. if you have og+rw permission, if I'm not wrong, it means that only group and user have permission but not the user, try to add the read/write permission to the user also
