I had exactly the same problem on yesterday. When I tried to run "wo stack install" I always got the error message that the phpMyAdmin package in /var/lib/wo/tmp could not be extracted. I also tried to run "wo stack install --phpmyadmin" but it won't work that way as well.
Today the problem seems to be gone by maaaagic. Everything works fine and I was able to run wo stack install without any further problems.
The error message was "could not extract \/var/lib/wo/tmp/pma.tar.gz"
