Bug#961093: cups: Wrong mime type when accessing localhost:631
Package: cups
Version: 2.3.3-1
Severity: important
Dear Maintainer,
for many months I had this issue, that prevents me from using
localhost:631 to configure CUPS.
$ wget http://localhost:631/
--2020-05-19 23:40:57-- http://localhost:631/
Resolving localhost (localhost)... ::1, 127.0.0.1
Connecting to localhost (localhost)|::1|:631... connected.
HTTP request sent, awaiting response... 200 OK

As you can see mime type is text/plain, where it should be text/html.
This makes Firefox simply display a html as text instead of interpreting
it as HTML and now showing any links.
If I force Firefox to show request http://localhost:631/admin a situation
is slightly better, however its mime type is unspecfied, but Firefox
fallbacks to trying to parse it as HTML.
It does so succesfully, but then loading extra resources fails:
Console log: The stylesheet http://localhost:631/cups.css was not loaded because its MIME type, “text/plain”, is not “text/css”.
Indeed:
$ wget http://localhost:631/cups.css

I would really appreciate fix for this.
