Description

Noticed while testing some changes to the updater:

2025-10-03T16:17:44+0000 BzQpH9dVFp [info] previous download found; resuming from 291.18MiB
2025-10-03T16:17:44+0000 BzQpH9dVFp [warn] fail to download archive from https://github.com/nextcloud-releases/server/releases/download/v32.0.0/nextcloud-32.0.0.zip. Error: 416

It's a bit weird, as 291.18MiB is the full size of the download. In the end we should handle the error 416 and do a full download.

FYI @joshtrichards since you implemented the resume logic.

Research direction

Trace the updater's archive resume logic and the handling of HTTP 416 responses, using the reported log and download URL as the starting case. Reproduce a previously completed archive download and verify that a 416 response causes a full download instead of failing.
