I've been so glad the update did work in the end but now it's not usable anymore. Only entry left on my device is in camera lens launcher, but selecting it doesn't do anything. So I searched for executable and guess what: there is none!
Package mbarcode-core, which I guess is supposed to ship the binary, only contains directory structure and copyright file. Other packages only contain plugins. Would be really cute if you could repackage core package again to contain executable too!
