Purposefully trying to break the Upgrade Tool: 1. At the start it listed 1856 packages to upgrade. 2. On package #2 I turned off my wireless LAN 3. No error messages...nor did the tool produce any indicators of loss of network connectivity to flag the user that something was wrong...the time remaining estimate eventually disappeared 4. I turned the wireless LAN back on after 5 minutes 5. The upgrade tool resumed where it left off with package #2. 6. At package #3 I unplugged the laptop (catastrophic power loss) 7. After rebooting and logging in, the Adept Updater icon showed in the system tray 8. I opened updater and it listed all the packages that needed updated to Feisty versions...just as I suspected the sources.list file was already modified to Feisty, so Adept is treating the system as Feisty when it is still Edgy. 9. The upgrade tool did not reopen. 10. I closed Adept and modified the sources.list back to Edgy 11. I opened Adept and fetched headers. 12. The upgrade tool automatically reopened, window remained blank except the status bar as it loaded Feisty headers (at this time I am unsure if that is an issue specific to my situation or an issue with the tool). 13. When headers finished loading, the tool GUI returned completely. 14. I restarted the downloaded package process and it began downloading where it left off when I catastrophically killed the power.
Summary: 1. Very positive feedback. The program is intuitive enough to know where it left off in the download process when bad things happen. This feature alone will save quite a lot of new user consternation when one considers the large time spans involved to do upgrades....mine now says 18 hours left. If I lost power or connectivity at 9 hours into the load and had to restart from the beginning it would be a very bad time here to say the least. So this part is very nicely constructed. 2. Things to consider. There needs to be some method that restarts the tool automatically after catastrophic power loss when the user has restarted the computer and logged in. The tool will will need to automatically reset the sources.list file back to the previous version in order to run. I am thinking that a simple file copy from a backup would work here. Of course, the tool will need some sort of admin permission to accomplish this so there is a security element also...maybe a dialog box that asks the user if he wishes to continue after noting a catastrophic failure. A "yes" gives the program permission to restore the previous version sources.list then continue running, a "no" to restore the previous version sources.list and exit the program. This ability to recover in case of catastrophic power loss may not be available for the Edgy to Feisty migration due to time constraints, but perhaps from Feisty to the next version would be possible. Based on previous test feedback I do not anticipate any difficulties completing rest of download with this tool....that is of course I do not lose power in my home before it finishes ;-) -- SRU: updates necessary for Kubuntu Upgrade Tool in Edgy https://launchpad.net/bugs/84717 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
