I've tried to update interwiki cache as part of T240771 earlier today, and dumpInterwiki.php created a change that doesn't seem to be right, as it added entries like # NOTE: This file is automatically generated. Do not try to edit it directly.:q.
Nothing obvious seems to be in dumpInterwiki's git log.
Can you try using scap update-interwiki-cache and see if that renders the same errors? Or is scap using dumpInterwiki.php as well?
(AFAIK the note at the top of https://wikitech.wikimedia.org/wiki/Update_the_interwiki_cache is no longer true and when promted by scap you should use your current gerrit credentials to commit the change; please ask @Reedy as he may know best though)
The scap plugin is indeed using that script, see https://github.com/wikimedia/operations-mediawiki-config/blob/master/scap/plugins/updateinterwikicache.py.

One's LDAP password works just fine too.
Please add a note what you are looking for when tagging Language-Team. We don't maintain this code.

[mediawiki/extensions/WikimediaMaintenance@master] dumpInterwiki: Respect comments in dblists
Thought you do, or at least know who could help :-). Anyway, I figured out what the issue is: We added comments to dblists, but didn't change dumpInterwiki.php to respect them. Uploaded a fixing patch.
