Dear maintainer,

trying to download .deb files or .tar.gz files from p.d.o. with Chromium Versione 93.0.4577.82 silently fails.

For example, go to https://packages.debian.org/sid/amd64/gnokii/download and click to a dowlaod link,
the download doesn't start, but the  browser's console shows this message:
Mixed Content: The site at 'https://packages.debian.org/' was loaded over a secure connection, but
the file at 'http://ftp.it.debian.org/debian/pool/main/g/gnokii/gnokii_0.6.30+dfsg-1.3_all.deb'
was loaded over an insecure connection. This file should be served over HTTPS. This download has
been blocked. See https://blog.chromium.org/2020/02/protecting-users-from-insecure.html for more details.

thanks,
Daniele

1. Open your terminal, and type 'wget *{download url}*'
2. Change the http in  '
http://ftp.it.debian.org/debian/pool/main/g/gnokii/gnokii_0.6.30+dfsg-1.3_all.deb'
to http*s*
3. Add 'deb http://ftp.de.debian.org/debian sid main' to
/etc/apt/sources.list, as it says on
https://packages.debian.org/sid/amd64/gnokii/download, then type in your
terminal 'sudo apt install *{package name}*'
4. Assuming you are on a Chromebook, as you talk about Chromium OS, Google
does not suggest this, but it is an option, you can enable developer mode
<https://medium.com/@dihuta/turn-on-developer-mode-on-chromebook-bd8a05c31bf9>.
This allows you to install apps from unknown sources, and hopefully
download packages using http. If you decide to do this, be careful about
what you download, as it can potentially be dangerous. It is legal, and
does not void your contract with Google, unlike jailbreaking iOS and
unlocking Android Bootloader. Still, I would not recommend this for
non-developers. It is highly unstable.

Hope this helps,
Kyle
