Can't install addons through paper ui any more

For some reason it stopped working for me to install addons using the paper ui. Whatever I search for in the ui it shows no addons at all. I know it worked in the beginning when I installed it. I know I can install addons manually too, but I like this new feature, especially if it makes it easier to find and upgrade them.

Embarrassing, apparently my backup (crashplan) filled my system disk with cache. Moved it to a better path now, problem solved…

Or well, I can search for stuff now, but when I install something, the wait animation just keeps going forever and doesn’t install anything… :frowning:
