I am running debian unstable, but upgrading only occasionally.
Now I have one package which gives an error message saying that dpkg cannot handle "data.tar.xz".
apt-get does not do much else than complaining about this, whatever I try to do.
After some googling, I believe the problem is that I am running a version of dpkg that is too old (184.108.40.206, but I would need >1.15.6, I think).
Any ideas how I can fix this?
Thanks a lot, A
