because I have renamed the kernel package (for reasons outside of our project - and independently on how you want to do it in the future), please run:
$ apt-get update $ apt-get install file $ apt-get remove kernel-image-omap2plus $ apt-get install quantumstep-linux-omap2plus-kernel
after that
$ apt-get update $ apt-get upgrade
should work for future upgrades as it did before.
BR, Nikolaus
