snap run nextcloud.occ maintenance:repair
snap run nextcloud.occ upgrade
snap run nextcloud.occ maintenance:mode --off

Preview generator

snap run nextcloud.occ preview:generate-all -vvv

Large existing file collections

Use Nextcloud Client to sync your local files to Nextcloud device, it may take some time. You may want to attach a disk with existing files, make sure they are in the right directory: /nextcloud/[user]/files Then Attach it to Syncloud device and activate in storage settings. Another way is to copy files to device into /data/nextcloud/[user]/files

Fix permissions

sudo chown -R nextcloud:nextcloud /data/nextcloud

File scan

Scan files to Nextcloud by running this command on the device:

snap run nextcloud.occ files:scan --all
