Comment 11 for bug 162470

Sorry for the late response I apparently didn't get Launchpad notification.

First, you need to install the flac package :
sudo apt-get install flac

(or use Synaptic)

Second, the script doesn't work for me anymore, and I don't know why it worked once but doesn't anymore, except maybe that some packages have been updated on the system. So use these 2 commands instead (but it's going to take a long time, since it will redo it even for files that already had a SEEKTABLE :

find . -name *flac -exec metaflac --remove --block-type=SEEKTABLE {} \;
find . -name *flac -exec metaflac --add-seekpoint=10s {} \;

4 files out of several thousand gave me some errors, but the rest was ok.
