I have installed ApplicationManager at Ubuntu 12.04

after starting I see following errors
in StartUpLogs_err2:
MySql daemon is not running on your linux machine/ PLease start daemon and retry.

in StartUpLogs_out2:
usermod: user postgres is currently logged in
waiting for connection in the database for Postgresql

as well, I have made two installation,
on same machine with different folders, and  not deleting first of them.
Same error happens for both installations.
