One of (apparently) your web pages presents a blank window, instead of
useful content.
https://debian-administration.org/article/schroot_-_chroot_for_any_users
Using <CTRL>-U to view the HTML source displays the following (again,
after having appeared to have first transmitted many bytes):
<!DOCTYPE html>
<html>
<head>
<meta name="generator" content="HTML Tidy for HTML5 for Linux version
5.2.0">
<title></title>
</head>
<body>
</body>
</html>
The page is one of the first hits displayed in the results of a Google
search for *"schroot for dummies".*
It give the appearance of sloppiness at Debian, but I suspect that's
not the case, as the organization displayed by *whois* for the domain
debian-administration.org
<https://debian-administration.org/article/schroot_-_chroot_for_any_users>
does not match that shown for the domain debian.org
