Is see there is an error deleting the xbt file and reading addon information. Don't know how this happened. Are some files read-only? Can you chack if addon.xml is readable?

it's readable. but if check ter entire folder it says "something" is "read only".
dont know if it's related but i've upgraded to kodi 16 yesterday, worked with 15.2 and skin version 3.1.6 (or 3.1.5). if i open a fresh copy of kodi i have no problems installing/updating from the repo.
only when updating the skin on my current copy of kodi.

That's probably the problem, you need write access to change settings. I don't know how it has got read-only. I cannot change permissions with the skin. When you change the permissions to read-write your problem should be solved.

Thanks,
Helly.

already did that, didn't help. i'll just update using the zip file from now on.

edit:the read only isn't going away even after i remove it for some reason.
