Public bug reported:

Binary package hint: release-upgrader-apt

When upgrading to Hardy Heron 8.04 LTS, it is possible to run programs
and restart the computer. If I run programs, most of them will be broken
because they will be half updated. If I restart the computer, it does
not resume the installation and it does not boot properly.

My mother in law was running 7.10 and selected the upgrade to 8.04 LTS
option. During the installation, the upgrader asked a question about a
change to the cups.conf file ( which I had changed ). She did not notice
the question, thought the installation was complete and restarted the
computer. When the computer restarted, it opened up gnome which did not
finish loading and did not give any error message.

In order to resolve the issue, I went down to terminal 1 ( CTRL + ALT +
F1 ) and as root ran "apt-get dist-upgrade". It resumed the upgrade,
finished installing everything. I restarted and the computer worked
fine.

Things that should be improved in installer to make the upgrade more
user friendly :

1. If user tries to restart the computer during an upgrade, the user should see 
a warning saying that the operation could seriously break the computer ( or 
simply disable the shutdown button ! )
2. If the upgrade asks the user for information, the window asking the 
information must be very obvious, perhaps flash until the user answers ?
3. If the upgrade is interrupted, it should be automatically resumed when the 
computer restarts. In my MIL's case, she was unable to get as far as gnome. 
Perhaps the upgrade could have pulled her down to tty1 and completed the upgrade
4. Upgrade should have a "download only" option
5. Perhaps the upgrade should run by itself and other programs should not be 
allowed to run at the same time 

( not sure if I selected the correct package, whatever packages causes a
computer to be upgraded using the orange notification icon )
