Hello, Per https://backports.debian.org/Instructions/#index1h2, you should be installing specific backports instead of all that are available. Specifically, this means you should run apt-get upgrade / dist-upgrade without "-t stretch-backports". Likely what's happening is that apt installs some library backports which are incompatible with its stable version, causing packages depending on them to be removed.
John’s advice here is super-germane; as it happens, I tried just sudo apt-get -t stretch-backports nvidia-driver two days ago on a similarly vanilla (albeit gnome3) system, and saw shenanigans with it trying to smoke the x install.
Something may be messed up in the dependancies there on amd64, as the tool returns “candidate package does not exist” when you try to reinstall nvidia-driver…..
Cheers! Best, James On 2018-05-07 04:21 PM, John Smith wrote: Hi,
I am on a fairly pure debian stretch xfce desktop, I added the
backports repo and because I just want to have all the upgraded
packages, so I did
apt-get -t stretch-backports upgrade && apt-get -t stretch-backports
dist-upgrade
some days ago (after putting backports repo into /etc/apt/sources.list).
Until now that caused no problem and helped me to make the nvidia
hardware actually work with the driver version in backports, also I
like the 4.15 kernel very much as it seems to make the desktop
experience much smoother. So everything ok and a great system overall.
However, today I just wanted to upgrade the same way (no special
reason, just routine upgrade) and apt-get wants to autoremove half of
the system and remove some important things - why?
I paste the output of the command below - it would be really
appreciated if anybody would like to explain
* why that happens
* what went wrong
* how to fix that.
cat /etc/apt/sources.list
