I tried this:
sudo -u www-data php occ maintenance:mode --on
sudo redis-cli -s /var/run/redis/redis.sock
auth XXXXXXXX
flushall (OK was response)
exit
sudo -u www-data php occ maintenance:mode --off
sudo -u www-data php occ files:scan --all
On the last line I hit this error:
sudo -u www-data php /var/www/nextcloud/occ files:scan --all
"
Starting scan for user 1 out of 4 (Adam)
Home storage for user Adam not writable
"
In previous attempts to sort this out today I’ve run
chown -R www-data:www-data /var/www/nextcloud/
So I am unsure why it would be unwritable
