Repo no longer available

Fresh install of Tumbleweed, and trying to install various extra programs, and keep getting message half way through install that says:
Cannot access installation media
https://download.opensuse.org/repositories/openSUSE:/Tumbleweed/standard/openSUSE:Tumbleweed (Medium 1)
Has happened so far for scrcpy/signal/kodi and a couple of others.
If you try and open the url, get a 404 error - resource is no longer available.

Thanks.

Extra: Just realized also doing it for zypper dup…
How can I TOTALLY reset my repos…?
Thanks.

Post your repositories with URLs:

$ zypper lr --uri

The packages you mention are not in the main OSS repository, but you might have wrong repository URLs anyway.

OK, think I have sorted - was a stray repo, not sure where it had come from, disabled, and all now appears OK.
Repos are obviously carried forward in you profile even when a complete new build done…?
Must remember that - maybe disable repos before a reinstall??
Thanks.

I don’t think so. They are kept in /etc which lies in the main subvolume, not in a profile. They wouldn’t be kept from a previous install.

Do you know where: https://download.opensuse.org/repositories/openSUSE:/Tumbleweed/standard/
would come from?
I disabled it, and all seemed to start working, but then it duplicated itself in the repo list, and breaks things again!!
Second delete, and now all appears to be working again - confused!!

Thanks.

Not sure, but

$ curl --head https://download.opensuse.org/repositories/openSUSE:/Tumbleweed/standard/
HTTP/2 302
location: https://download.opensuse.org/tumbleweed/repo/oss/

redirects to the canonical URL for the main OSS repo. Matches my system. Never seen zypper duplicate a repo before.
