in the app store the newest release is 1.2.8 (platformVersionSpec >=30.0.0 <33.0.0) and this catalogue ships Nextcloud 34, so the store offers nothing this server can install and files_archive is not server-shipped — occ app:install cannot succeed. On a deployment that climbed, the hop to 33 already disabled it. Acknowledge only when the target server is on rung 31 or 32.
