Package: libstdc++6
Version: 6.3.0-18+deb9u1
Severity: important
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Installing g++-8 on Debian Stretch through the Debian Buster
repository. Previously (some months ago) this was possible;
I've done it several times, but some day, the dependencies
changed, and when I updated g++, my system broke (I didn't check
the warning from apt-get, which I should have done). When I
did a clean install of Debian 9, I tried to do it again, and
found that the dependencies of g++ caused xorg to be removed,
and tracked it down to libstdc++6.
* What exactly did you do (or not do) that was effective (or ineffective)?
I read the dependencies of libstdc++6 through this command:
$ apt-get install --simulate -V libstdc++6
$ apt-cache showpkg libstdc++6
* What was the outcome of this action?
I expected a dependencies list that does not try to remove xorg.
* What outcome did you expect instead?
$ apt-cache showpkg libstdc++6
[...]

don't do that. it's not supported to install packages on releases that they are
not built for. You could build gcc-8 on your own, if you want.
