Hi, thanks for the quick answer!
You need to keep all the versions matching for the Android Tools packcages, e.g. 8.1.0+r23. When the fastboot update comes, they'll all work again. Or you can go back to 8.1.0+r23 for all the packages.
Yeah, I understand that.But why not force that via dependencies like for the "android-*" packages:
Version »1:10.0.0+r36-1~stage1.3« (Debian:unstable [amd64]) für »android-libadb« gewählt aufgrund von »adb«. so that it "just works" for the user?
