Public bug reported:
Binary package hint: update-manager
During the Karmic release cycle, MySQL has been updated from 5.0 to 5.1
in main. That means that the mysql-server binary package is now
depending on mysql-server-5.1 instead of mysql-server-5.0. update-
manager already supports upgrading mysql-server from 5.0 to 5.1 - see
bug 413789.
However there is one use case where the upgrade should not be done. If
mysql-server is setup as part of a MySQL cluster (ndb engine), the
system should not be upgraded to 5.1. Instead the mysql-server binary
package should be removed (as it would pull 5.1 in) and 5.0 should be
upgraded instead (which is in universe in karmic).
There is already a check in mysql-server-5.1.preinst script that tests
if the ndb engine ise used. If so it aborts the upgrade by printing a
message:
# Abort if an NDB cluster is in use.
if egrep -qi -r '^[^#]*ndb.connectstring|^[:space:]*\[[:space:]*ndb_mgmd'
/etc/mysql/; then
db_fset mysql-server/no_upgrade_when_using_ndb seen false || true
db_input high mysql-server/no_upgrade_when_using_ndb || true
db_go
db_stop
exit 1
fi
Removing mysql-server should be done before an upgrade is performed.

If mysql is configured to use the ndb engine a karmic upgrade should keep
mysql-dfsg-5.0 and remove the mysql-server package
