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 Length: 2295 (2.2K) [text/plain] Saving to: ‘index.html’ index.html 100%[=====================================>] 2.24K --.-KB/s in 0s 2020-05-19 23:40:57 (303 MB/s) - ‘index.html’ saved [2295/2295] $ 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”.
