Log Location for Web Update Process

I have a very old Nextcloud 20.0.14 instance that has been failing to upgrade using the webupgrade function. It downloads, goes into maintenance mode, and starts the upgrade but fails without displaying any helpful error other than something like upgrade failed.

Can someone help me find the location of the log file created during a webupdate to help me dig into specifically why this is failing?

My install path is /var/www/nextcloud. The only log folders in there seem to be related to apps or 3rdparty.

The Updater logs in updater.log located in your configured datadirectory.

If the Updater completes, then the db migrations and app upgrades run after that. Those will be logged in the standard nextcloud.log located in the same location.

Thank you! I had to revert after the last failed upgrade to keep things functional but I will re-try and check there for the logs.
