Failed to install TVheadend in Debian bullsesye x64

Today I was trying to install unstable TVheadend in Debian bullsesye x64 according to the instructions in
https://tvheadend.org/projects/tvheadend/wiki/AptRepositories.

After adding the repository "deb https://apt.tvheadend.org/unstable/ bullseye main", the apt installation failed with message:

Err:1 https://apt.tvheadend.org/unstable bullseye/main amd64 tvheadend amd64 4.3-1991~g3ed76138a~bullseye
404 Not Found [IP: 172.67.206.223 443]
E: Failed to fetch https://apt.tvheadend.org/unstable/artifacts/o2/ar6jzkjn/tvheadend_4.3-1991%7eg3ed76138a%7ebullseye_amd64.deb 404 Not Found [IP: 172.67.206.223 443]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

Is the repository settings wrong? And where can I find the deb file of TVheadend?

Thanks in advance,
Hazuki

There's an accepted bug report for this, I'm having the same problem with focus.

According to Mark Clarkstone:

all builds that use ffmpeg are failing

You can install an older version by following black_eagle's post on the Kodi forum

Thanks for the hint. After checking, the commit https://github.com/tvheadend/tvheadend/commit/07b3d405f85731abe5b6310b787074e1f8233d5f breaks the build. Revert it shall fix.
