Bug Description

Binary package hint: upgrade-system

Using a 57K phone modem, upgrade from 7.10 32-bit Kubuntu to 8.04 takes about a week. During that period it is likely that the KPPP daemon will die at some point. The installer offers no option to resume the install, but insists on aborting instead. What is so time critical that it cannot wait? Perhaps this is a feature request, not a bug report, but whatever it is called, this is a serious problem with the installation software from my perspective. Phone modem users are not sub humans. Thanks for your time.

I followed the procedure outlined on
https://help.ubuntu.com/community/HardyUpgrades/Kubuntu for online
upgrading. I am not certain what the name of the invoked package is.
Adept Manager invokes it. The window shown in step 9 of that page shows
the window that is active until the phone line flakes out. In my case,
this step takes about a week, which would be a rather large cup of
coffee.

This appears to be "normal operation" for the upgrade installer. In
other words, it is apparently supposed to abort when the phone
disconnects. You could duplicate the sequence of events on any machine
that is not upgraded to 8.04. Just follow the instructions on that page
until you reach step 9, then disconnect from the Net some how. The
upgrade installer will probably abort for you as well.

I will add these details to the bug report page.

My point is that there should be a "resume" button available to click after the connection is restored.

Thanks for your bugreport.

This is indeed a missing feature, however it should not loose any downloaded data. That means, even if the upgrade aborted, when you run it next time, it should pick up from the point were it got disconnected.

Thanks for the info. When I reconnect it takes about 30 to 35 minutes of "setting channels" before it resumes where it left off downloading files. At the very least, this should be added to the aforementioned help page, that "the upgrade aborts now" does not mean all the downloaded files are lost. It's simple stuff like this that makes a huge difference to a newbie.

Thanks, that does indeed make sense. I updated the text to:

+ _("The upgrade aborts now. Please check your "
+ "Internet connection or "
+ "installation media and try again. All files "
+ "downloaded so far are kept."),

Do you think that this is more clear now?
