Setting up mythtv-database (0.23-0.1) ...
Failed to execute SQL: GRANT ALL PRIVILEGES ON mythconverg.* TO mythtv@localhost IDENTIFIED BY '3zRkyO86'\nAccess denied for user 'root'@'192.168.80.4' to database 'mythconverg' at -e line 8, <> line 1.
dpkg: error processing mythtv-database (--configure):
subprocess post-installation script returned error exit status 255
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)
Is there a solution ?
Remove and reinstall Mythtv on MD don't resolve this.
