I have NextcloudPi installed on SBC which has a external drive attached to it, this is my private cloud solution. Today I was getting internal server error on login to nextcloud so I updated the Nextcloud to 15.0.7, then I got message saying don’t forget to run nc-init which I did but the I see all the users are gone and even the data in external drive. I was not aware that running nc-init will wipe out all users and data in external hard drive. I am so upset that all of my data is gone, specially my picture and important documents.
Please help me get them back if possible.
