嘗試從 Bullseye-backports 安裝軟體包

我正在執行 Debian Bullseye，我想安裝 ffmpeg 4.4.1，它看起來在 sid 中​​可用：

所以我添加了backports repo：

# apt-cache policy
Package files:
...
500 http://mirrors.ocf.berkeley.edu/debian bullseye/main amd64 Packages
    release v=11.2,o=Debian,a=stable,n=bullseye,l=Debian,c=main,b=amd64
    origin mirrors.ocf.berkeley.edu
100 http://deb.debian.org/debian bullseye-backports/main amd64 Packages
    release o=Debian Backports,a=bullseye-backports,n=bullseye-backports,l=Debian Backports,c=main,b=amd64
    origin deb.debian.org
...

# apt-get install -t bullseye-backports ffmpeg

ffmpeg is already the newest version (7:4.3.3-0+deb11u1).
0 upgraded, 0 newly installed, 0 to remove and 33 not upgraded.

apt-cache show ffmpeg僅顯示一個條目，它用於主穩定儲存庫中的 ffmpeg 4.3。有什麼建議嗎？

似乎 ffmpeg-4.4.1 不在 Bullseye backports中。如果你真的想使用 4.4.1，你必須添加 debian testing repos，但**不要輕易這樣做**！
