I want to install mesa 18 from stretch-backports. Currently all the mesa related packages were marked as automatically installed and I want to keep it that way.

If I simply do

$ sudo apt upgrade -t stretch-backports

It updates mesa but also too many other programs. Is there way to only upgrade packages coming from the mesa source package? Or maybe apt-pin based on source package instead of binary package?

You should always avoid upgrading using -t stretch-backports since backports aren’t a coherent set of packages.

To upgrade all Mesa packages without marking them as manually installed, install them and then unmark them:

sudo apt install -t stretch-backports $(grep-status -S mesa -a -FStatus "install ok installed" -s Package -n | sort -u)
sudo apt-mark auto $(grep-status -S mesa -a -FStatus "install ok installed" -s Package -n | sort -u)

This lists all installed packages which come from the Mesa source package, using grep-status (part of the dctrl-tools package), installs them from backports, and marks them as automatically installed.

    @Anees see the introduction to backports. Full releases of Debian are tested as a whole; backports are tested as small sets of packages (typically the packages from a single source package) on top of the release they target, without consideration for other backported packages. As a result, there’s no guarantee that backported packages will work well with each other. – Stephen Kitt Feb 25 at 8:27
  • Got it. Thanks. Note that I had to install dctrl-tools first in order to get this working. – Anees Feb 25 at 9:03
