Hi, nice bug number btw :-)

I currently try to clear dormant bugs.
Looking at your log I see:
 mysql_upgrade: Got error: 2002: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) while connecting to the MySQL server

That is a known issue that you can find on launchpad, I'll mark your report as a dup and ask you to read details from there.

In general the issue can be resolved by retrying the upgrade/install.
