Description

Steps to replicate the issue (include links if applicable):

Download the image file (source: Fandom).
Ensure that the wiki has "Spectre_and_Intel_logos_combined.png" (on my wiki).
Try to upload the first file.

What happens?:
The page states that the two files have the same name and the one I am uploading will overwrite the one already on the site. However, they do not share the same name. In fact, the names are very different from each other.

What should have happened instead?:
Nothing should have happened, the two files have very different names.

Software version (skip for WMF-hosted wikis like Wikipedia):
MediaWiki 1.40.0
PHP 8.1.2-1ubuntu2.14 (fpm-fcgi)

Other information (browser name/version, screenshots, etc.):
Using Firefox Browser 117.0 (64-bit).
More detailed version and library info can be found on the wiki itself:

This is because on Commons, File:Meltdown.png redirects to File:Spectre and Intel logos combined.png, which means File:Meltdown.png do exists on your wiki: https://ntmwiki.u-group13.org/wiki/index.php?title=File:Meltdown.png.

This is not very obvious currently. Maybe the error message should have used the actual redirect name that matches. But then if it tells you File:Meltdown.png exists, you might be confused with what https://ntmwiki.u-group13.org/wiki/index.php?title=File:Meltdown.png&redirect=no currently shows (no hint of what is happening)

Why does that redirect exist anyway? It couldn't've been of my creation,
I pretty much just setup the wiki when I began trying to upload files to it.

It exists because you're using $wgUseInstantCommons (or something equivalent to that). You can disable the feature if it's confusing to you.
