It can take a very long time I guess to this last step to happen.

Note that if it fails at the end or never succeed even after 1 hour, you'd better contact the author of this plugin.

Hi @dadoonet, as a plugin author, what's the best way to debug this situation? Is there a verbose mode for the optimisation process? What would you look into? Would appreciate **any** pointers to start debugging.

In my case, the customer has reported that:

- They manage to install my plugin only on freshly unzipped Kibana (the issue happens only after re-installing my plugin)

- They do not have any other plugin installed when this happen.

- They use linux.

- If they kill the process after 5 minutes, the plugin looks perfectly installed anyways. So whatever is hanging, it's hanging very late in the process.
