Is your database corrupted per chance? have you tried to run the standard repair on all the tables?
If that's the root cause here, there's not much we can do. If that doesn't help out, can you please add "set -x" to the second line of /var/lib/dpkg/info/mythtv-database.postinst and run dpkg-reconfigure mythtv-database? The output of that should help us debug what's going on. ** Changed in: mythbuntu Status: New => Incomplete -- package mythtv-database 0.22.0+fixes23003-0ubuntu0+mythbuntu3 failed to install/upgrade: could not backup or apply new schema to mythconverg https://bugs.launchpad.net/bugs/501732 You received this bug notification because you are a member of Mythbuntu Bug Team, which is subscribed to Mythbuntu. Status in Mythbuntu, Ubuntu derivative focused upon MythTV: Incomplete Bug description: Upon upgrade from mythbuntu 0.22 to 0.22.0+fixes23003, installer crashed. The installer indicated it would upgrade the mythconverg schema but it was unable to create a backup. I proceeded (knowing I have a manual backup). The installation then failed: unable to update schema for mythconverg, which also caused the myth-backend and master backend upgrade to fail. Manually running mythtv-setup also fails with the same errors. This system was originally upgraded from Mythbuntu 8.10 (mythtv 0.21) to Mythbuntu 9.10 (mythtv 0.22). I have been trying to import the recordings tables from the original Mythbuntu 8.10 partition but with little success (recordings after April 10, 2009 have a reference in MythTV and the .nuv files appear in the recordings directory but they are not available for viewing within MythTV). Possibly this database issue is related to the failed setup.
