Can't update WEBMIN in Ubuntu24.10

Webmin
1
SYSTEM INFORMATION
OS type and version Ubuntu.24.10
Webmin version Webmin 2.202

I get this when I update Via Apt: “Ignoring file ‘webmin.list.migrate’ in directory ‘/etc/apt/sources.list.d/’ as it has an invalid filename extension.”
What is the correct file name extension?

just .list not .list.migrate, you may have webmin.list already so you can delete the .migrate file, if not just rename the .migrate to .list
so from webmin.list.migrate to webmin.list
