Nextcloud version (eg, 12.0.2): 13.0.1
Operating system and version (eg, Ubuntu 17.04): Raspbian mit ubuntu 16.04 LTS
Apache or nginx version (eg, Apache 2.4.25): ? (Installed in August 17 )
PHP version (eg, 7.1): Installed in August 17…
setup: Raspbian with Nextcloud and a mounted share with a Synology as file server
The issue you are facing: until two weeks back, every worked perfectly. then I had some power outages in my appartment and afterwards syncing didnt really work at all anymore. I was frustrated and my solution was trying a new User for a clean sync start and Hey, it worked perfectly! since then, no problems at all. Syncing was great.
Now, I had another power outage and afterwards my new user (and a newly created shared folder) are GONE! they do not exit in Nextlcoud any longer. What I now did: I created the exact same user and all my files showed up (remember, they are stored on the synology). What I did next is reboot my raspPI with sudo reboot and again! the new user is gone!
From my own install documentation, I used the following commands again before reboot, just in case, but apparently, it didnt help:
a) sudo chown -R www-data:www-data /var/www/html
b) in mariaDB: grant all privileges on nextcloud.* to nextcloud@localhost;
flush privileges;
Is this the first time you’ve seen this error? (Y/N): y
