Hello, fellow Debian users.
When I need to build a backport of a package, I sometimes find it
difficult to obtain actual source package(-s) from Debian repos using
console.
Following advice from a wiki page [1], after "apt update", doesn't do it:
$ apt source lego/testing
Reading package lists... Done
Picking 'golang-github-xenolf-lego' as source package instead of 'lego'
E: Can not find version '3.2.0-3.1' of package 'lego'
E: Unable to find a source package for golang-github-xenolf-lego
Any other seemingly intended ways also fail in a similar fashion:
$ dget lego=4.9.1-1
dget: no hostnames in apt-cache policy lego for version 4.9.1-1 found
$ apt-get source lego -t testing
Reading package lists... Done
E: The value 'testing' is invalid for APT::Default-Release as such a
release is not available in the sources
E: Unable to find a source package for
Trying to do the same for another package seems to work:
$ apt source ipcalc/testing
Reading package lists... Done
Selected version '0.42-2' (testing) for ipcalc
Need to get 33,7 kB of source archives.

dpkg-source: info: extracting ipcalc in ipcalc-0.42
dpkg-source: info: unpacking ipcalc_0.42.orig.tar.gz
dpkg-source: info: unpacking ipcalc_0.42-2.debian.tar.xz
dpkg-source: info: using patch list from debian/patches/series
dpkg-source: info: applying 01-paths.patch
So why those fail for a "lego" package and is there a way to solve this
once and for all?
I know I can go to a packages website [2] and manually download ".dsc"
file and feed it to "dget" utility, or download source files directly
from said website, but there has to be a better way.
Some useful info:
$ cat /etc/apt/sources.list | grep -iE "testing"
