Comment 9 for bug 442941

I just installed Ubuntu 11.04 on a blank Linux-Ubuntu virtual machine in Oracle VirtualBox (4.0.6), and when attempting to run Software Update, I get the following error messages:

Package operation failed
installArchives() failed: Setting up tzdata (2011g-0ubuntu0.11.04) ...

Use of uninitialized value $reply in scalar chomp at /usr/share/perl5/Debconf/FrontEnd/Passthrough.pm line 66.

etc...

The workaround from comment #6 solves the issue.
