Aborting Upgrade

Nextcloud version (eg, 12.0.2): 15.0.2
Operating system and version (eg, Ubuntu 17.04): Ubuntu 18.04
Apache or nginx version (eg, Apache 2.4.25): apache with nginx
PHP version (eg, 7.1): 7.3

The issue you are facing:

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

No steps to reproduce, maybe its my fault. I want to upgrade to the newest version, but the web based installer failed. Actually the page shows me to start the upgrade. Is there any way to stop the upgrade. I know whats going wrong, but im not able to abort the upgrade process. Maybe delete someting or edit something?

This is the window what i’m talking about.

Hope anyone can help me :slight_smile:

If you have gotten that far in an upgrade you will have to restore a backup to get it back. You can always try the occ upgrade command first that might work if the web based fails.

btw: you should not skip major versions while updating. so please do update to nc16.x at first and then to nc 17.x
