I have a Nextcloud instance on a shared / webhosting environment installed and no command line interface available.
The web based updater failed while doing and backup. Is there a way to manually upgrade the instance without the CLI? I did read the admin manual, but there the final upgrade step is done with occ on the command line.
Nextcloud version (eg, 12.0.2): 16.0.6
Operating system and version (eg, Ubuntu 17.04): ??
Apache or nginx version (eg, Apache 2.4.25): ??
PHP version (eg, 7.1): 7.2
I think I have read anywhere that you can disable maintenance for a user even while updating.
I would suggest to kick off the update, go to config and set maintenance mode = true. Then try occ web.
I have the same problem. The update crashed. This is because of the php time limit on shared webspaces.
Luckily I have SSH on my webspace and it works updating this way
