I have the same problem in a clean install of 10.04 (iso downloaded today). I believe I had the same problem when I did an upgrade of 9.10 to 10.04 yesterday - I had to kill the install of mysql-server which had hung, but I've done the complete install today.
Synaptic hangs on start mysql and the install can't complete. Same thing if I uninstall the half installed version, and when I reinstall again.
