I installed Debian jessie on a laptop with relatively new hardware, e.g. a Skylake i7-6600U processor, so I had to install the kernel and firmware-iwlwifi driver from jessie-backports. /etc/apt/sources.list has this linedeb http://ftp.us.debian.org/debian/ jessie-backports main non-free contribI then installed linux-image-4.5.0-0.bpo.2-amd64 and firmware-iwlwifi=20160110-1~bpo8+1. Now that these are correctly installed, does it make sense to remove that line from /etc/apt/sources.list?I'd like these packages to receive updates from the backports repo if any are available, but I don't want any other packages to get updates from jessie-backports. I have APT::Default-Release jessie; in /etc/apt/apt.conf.d/70debconf, so that should be enough to guarantee this, right?
I installed the kernel and some drivers from jessie-backports. Should I leave the backports repo in /etc/apt/sources.list?
debian;apt;backports
As https://backports.debian.org/Instructions/ says:All backports are deactivated by default (i.e. the packages are pinned to 100 by using ButAutomaticUpgrades: yes in the Release files.So backports are set to 100 server side - i.e. in the Release file on the server. You do not need to do anything special to make this work. One of the consequences is that you will be upgraded to new versions of the backports that are already installed, if/when they become available. However, no new backports will be installed unless you explicitly install them withapt-get install -t jessie-backports pkgnameSo you want to leave the backports line in there.
