Hmm guys, but this question here actually make sense to me. I'd like to update any software, but for example: After I get PR 1.2 and successfully installed MyPaint, 4 days later there is an update available. This time keep telling me "unable to update". Same PR, I didn't actually mes up anything uninstalled or installed anything new. But this update reminder keep popping up every day. Same situation with 2 plug-ins for conversation. I was trying to disable repos in many different variations, nothing helped really. I've received 3 more today and those was successfully updated.

4 months ago when I bought my N900 everything was clear with App manager. Any of installation or update never failed. Now seems to me like somebody needs to really take care about all this mess and package inconsistency over there.
