Hey Alkis, thanks for your bugreport and your analysis. This looks like its indeed a problem in the communication for password via debconf that may require additional privs.

But when installing from software center, the following debconf questions don't appear: (from debian/config): if [ ! -f /etc/phpmyadmin/htpasswd.setup ]; then db_input low phpmyadmin/setup-username || true db_input low phpmyadmin/setup-password || true fi This results in an endless loop, where a debconf dialog is presented mentioning that the db configuration failed and asking for abort/retry/retry (skip questions). Maybe the solution is to increase the db_input priority?
