How to check which version of a program in debian wheezy backports?

Question

linux

Hello!
It seems that backports do not work for me now on debian wheezy.
In my sources.list it is now written at the very end after the main repositories:
deb http.debian.net/debian wheezy-backports main
I'm trying to install lmms from backports with the command:
apt-get -t wheezy-backports install lmms
But for some reason I get lmms version 0.4.10 - although it says here that testing already has version 1.0.3-5
https://packages.debian.org/source/testing/lmms
What am I doing wrong?
It seems that the backports somehow do not work on my machine.
Thank you in advance for your help!
Sincerely,
Alexander

Answer 1

testing and backports are completely different repositories.
testing - repository of the next (currently being tested) debian.
backports - packages backported to the current stable-debian. Of course, not all packages from testing are backported - there are not enough hands, and some packages cannot be backported at all (due to incompatibility with packages in the base repository).
If you need a package from testing - include it with a minimum priority:
deb ftp.us.debian.org/debian testing main contrib non-free in /etc/apt/sources.list
In /etc/apt/preferences:
Package: *
Pin : release a=testing
Pin-Priority: -50
Then packages from testing will not be installed until you explicitly specify the version from testing when installing the package (this is necessary so that apt-get upgrade does not break half your system. And installing a regular package in stable with testing enabled can break firewood ).

I don't understand anything. Here I'm looking, it turns out that there is no fresh lmms at all in wheezy-backports?
https://packages.debian.org/search?suite=wheezy-ba...
The same goes for chromium-browser. It's just not in wheezy-backports:
https://packages.debian.org/search?suite=wheezy-ba...

Connect testing repository
Application version is very simple: apt-cache policy package name
