Are you working with your package manager's absolute latest updates
that are drawn from the repositories? By that I mean and as
example.... I use "apt-get" to install my packages. Others use
synaptic and/or aptitude.

For apt-get, I FREQUENTLY run the following from a terminal:

apt-get update

If you already knew that, my apologies in advance. Somewhere there
will be a newcomer who didn't. :)

I'm headed back outside right now to do more yard work but high on
today's to-do list was to *try* to catch back up on this very topic
here. As of very early yesterday morning, all those problems have
disappeared off my own unstable versions. That's why I suggested the
very basic thought of updating our package managers.

NOTE: The rest of this is "meandering" on my own last couple days in this.....

The previous errors I had that involved "libstdc++6" disappeared
couple days ago. Those involved programs wanting to autoremove
libreoffice. The NEW and similar errors began involving inkscape.
Caused inkscape to be uninstallable in my newest pure/clean
debootstrap. Also caused inkscape to be removed by too many other
totally unrelated programs in my previous "stable" unstable (several
months old) debootstrap copy.

* * * Afterthought note there: Inkscape's in there with blender.
Fingers are crossed that a fix is coming soon for blender's omissions,
if not done already. :) * * *

In my brand new and thus basically "empty" debootstrap here, gparted
drug in a couple dependency packages that were previously deemed on
hold for any inkscape install attempts. That same gparted was at that
moment simultaneously trying to REMOVE inkscape in my "stable"
unstable copy.

At first I was thinking gparted FINALLY dragging in some "on hold"
dependency packages in the newest empty/clean debootstrap might hint
at a possible backdoor for these problems. Smacked myself in the head
just now because I realized it was probably because those couple
dependencies had just been fixed by Debian developers.

It was interesting to watch the upgradeable list of packages appear to
change without any (conscious) action on my part. Best as I could tell
from this end, some of THAT.... is because there was a phenomenal
amount of unrelated packages installing each other. In the days just
before, those packages had been *theoretically* irreversibly
UNINSTALLING each other.

When packages INSTALL each other, the process occurs a lot more
quietly *IF* you don't stop and read/comprehend the verbose output
before you tell a package manager to go ahead and complete the
install. Makes it easier to not "see", to miss what's been going on
under the hood.

Goodness, I hope some of that makes sense. Sorry I didn't have an
answer, just wanted to note that my experience went a certain way,
ended up very positive, and reflects that Debian developers are
definitely busting backside on this. That observation is based on the
progress that could be seen while running "apt-get update" multiple
times a day over the last week.

PS.. An afterthought on this for newcomers: Some things that helped me
not miss a beat in daily computing through all this included knowing
how to move things like .config files in between the various copies of
distros I play with here.

The ability to move around between multiple distros/releases comes
from having self-taught myself how to create PARTITIONS. Those are
FRIGHTENING at first but have been GREAT toys, oops, TOOLS in
instances like this past week.

ALWAYS have umpteen backup copies of whatever last distro copy of your
own was working 100%...

!!-*_ALWAYS_*-!!

Don't be a hard head about HAVING to go pure unstable when unstable
hits a bump like this past week. Keep a very stable *stable* copy of
Debian around just for kicks, too. PPS.. That last one falls under....
don't do as I do... yada-yada.. *GRIN*
