Make your backports of a package

You can follow the instructions on SimpleBackportCreation to make a backport of a package. To do that without change your local system, you can use chroot, docker or other container tools to install deps and prepare the package.

For instance, we can do a backport of Inter fonts from testing to stable following the instructions from the link above: 

[host]$ mkdir -p .volumes/mnt/shared
[host]$ docker run -it --rm --volume=$(pwd)/.volumes/mnt/shared:/mnt/shared debian:bullseye-slim /bin/bash
[docker]$ apt-get update
[docker]$ apt-get install packaging-dev debian-keyring devscripts equivs
[docker]$ rmadison fonts-inter
[docker]$ echo deb-src http://deb.debian.org/debian/ testing main >> /etc/apt/sources.list
[docker]$ apt-get update
[docker]$ apt-get source fonts-inter/testing
[docker]$ cd fonts-inter-3.19+ds/
[docker]$ mk-build-deps --install --remove
[docker]$ dch --bpo
[docker]$ fakeroot debian/rules binary
[docker]$ dpkg-buildpackage -b -us -uc
[docker]$ cd ..
[docker]$ mv *.deb mnt/shared/
[docker]$ exit
[host]$ cd mnt/shared/
[host]$ dpkg -i /mnt/shared/fonts-inter_3.19+ds-2_all.deb
[host]$ dpkg -L fonts-inter
