10.04 LTS installation going badly - I'm now stuck

Two days ago, just before 10.04 LTS was released into the wild, there were some security updates. I tried to install them. They included a kernel update and it failed with the following messages as copied from the dialog box:

E: linux-image-2.6.31-21-generic: subprocess installed post-installation script returned error exit status 1
E: linux-image-generic: dependency problems - leaving unconfigured
E: linux-generic: dependency problems - leaving unconfigured

Now, I ignore this since 10.04 was due the next day anyway so last night I tried the 10.04 LTS upgrade.

In two separate dialog boxes I got the following errors:

subprocess installed post-installation script returned error exit status 1
subprocess installed post-installation script returned error exit status 1

It was late and I had left the computer running and was to tired to pay much attention to what point in the installation this was happening. I figured there's probably a log file that will tell me that anyway. (but I don't know which one)

This morning I came back to it (I'd left the install running during the night as I was too tired to stay up) and was being prompted by a dialog box to keep or change a configuration file. Nothing relevant here - I just kept going.

Ultimately, I ended up at a dialog box regarding MySQL and Bacula and requiring the MySQL database admin password.

I did once take a look at Bacula but decided it was too complicated to set up at the time and I abandoned it. It is not currently installed. I don't recall ever setting up MySQL (but I may have) but what puzzles me is that I would have given it the same password as my user account, yet, when the dialog box appeared, it wanted that password and rejected it. A blank password didn't work either so in the end I was forced to skip it.

Now I'm at a point during the 10.04 LTS upgrade where, within the dialog box, there is the terminal and it's showing:

┌───────────────────┤ Configuring bacula-director-mysql ├───────────────────┐

Nothing I press on the keyboard moves me forward. I've tried clicking on the console window and pressing space, enter, o, and esc.

In desparation, even though it's a console window, I've tried clidking on <Ok>

The up/down arrows allow me to scroll the text a bit (there are two additional lines) but no other options are presented other than <Ok>

So how do I move forward?
