Environment: Debian 8.0 (Jessie), x64, KDE desktop, with armhf architecture added for cross-compilation to BeagleBone.
While building Boost 1.55, I needed the python package. Makes sense, as Boost has some Python integration stuff.
apt-get install python:armhf failed, on "held packagages" but that apparently is a known bug (I have no held packages).
apt-get install python-minimal:armhf was accepted but suggested removing a number of packages including a lot of Boost 1.55. That wasn't entirely weird because I had a native version (isntead of the correct
:armhf). However, that also removed the whole GUI dropping me at a text prompt (!).
apt bug, there is no way in the world why a python package for ARM should affect KDE for x64. But how do I get my GUI back?
