Redshift works well and does the same thing.

He already has a post on redshift.

Not doubting your post, I would use it too over f.lux.

It's not OK. PPAs are specifically for Ubuntu. Sometimes they will work but sometimes they will wreck your system.

I use Redshift on all my systems. It works well and has a native Debian package in the repository which should always be preferred instead of PPA.
Your post about Redshift says it is solved. Why do you ask again about f.lux? They both do the same thing.
I just posted instructions how to install Redshift tray applet in that thread so you can configure it more easily.

Is it ok? I think it is not ok. Why?

As many times it has been mentioned here on this forum, and else where, one would think the OP all ready knew this, guess they have not read any other posts, hmm just goes to show , So any way , Yes, you are righht, it is not ok, Why is it not ok ?
Please read this:
Don't make a FrankenDebian

Debian Stable should not be combined with other releases. If you're trying to install software that isn't available in the current Debian Stable release, it's not a good idea to add repositories for other Debian releases. The problems might not happen right away, but the next time you install updates.

The reason things can break is because the software packaged for one Debian release is built to be compatible with the rest of the software for that release. For example, installing packages from buster on a stretch system could also install newer versions of core libraries including libc6. This results in a system that is not testing or stable but a broken mix of the two.

Repositories that can create a FrankenDebian if used with Debian Stable:

Debian testing release (currently buster)

Debian unstable release (also known as sid)

Ubuntu, Mint or other derivative repositories are not compatible with Debian!
Ubuntu PPAs

But don'r just read the small part I quoted, read the whole page, it is educational.

I used to run f.lux when I ran Debian. You need to do this, it's clearly listed in the Github page:

Code: Select all
# Download fluxgui
cd /tmp
git clone "https://github.com/xflux-gui/fluxgui.git"
cd fluxgui

# EITHER install system wide
sudo ./setup.py install --record installed.txt

# EXCLUSIVE OR, install in your home directory
# The fluxgui program installs
# into ~/.local/bin, so be sure to add that to your PATH if installing
# locally. In particular, autostarting fluxgui in Gnome will not work
# if the locally installed fluxgui is not on your PATH.
./setup.py install --user --record installed.txt
# Run flux
