The updater.log says:

Problem

The question mark in updater-XXXX/downloads/nextcloud/apps/support/resources/Why the Nextcloud Subscription?.pdf seems to be a problem for unzip.

cc @jospoortvliet @rullzer could you rename the file? Seems to be a issue for some people.

It's now named "Why the Nextcloud Subscription.pdf". It was renamed in 15.0.0 and 14.0.4. So this should be okay now.
