Comment 2 for bug 637445

Setting up mawk (1.3.3-15ubuntu2) ...
update-alternatives: error: alternative link /usr/bin/awk is already managed by awk.before_restore_2010-09-04_15.05.02.479476.
dpkg: error processing mawk (--configure):
 subprocess installed post-installation script returned error exit status 2

This error message indicates local corruption of your /var/lib/dpkg/alternatives directory, not a bug in the mawk package. Closing as invalid.
