Python 3.14 added pathlib.Path.copy() which refuses source==target with OSError [Errno 22]. archinstall's sync_log_to_install_medium() calls .copy() on install.log to itself at __exit__ time, because by then the chroot mountpoint is already torn down and both source and target resolve to the same /var/log/archinstall/install.log. The install itself has already succeeded — the crash is in the log-sync cleanup. Patch is a pre-start sed on the live ISO that replaces the offending call with `None` (a no-op expression-statement keeping the same indent level). Lives on furtka-webinstaller.service as ExecStartPre so it runs before the first install attempt; idempotent, so service restarts don't re-trigger anything. Never touches the installed system — only the live ISO's site-packages tree. Real fix is upstream in archinstall (guard the copy when source and target resolve equal); this is a workaround until they ship it.
