"Resume" suggests that downloads are never cancelled

[Pat McGowan]

Currently if you pause, then force-quit the app, when you return it tells you the download failed and offers a chance to retry.

<https://wiki.ubuntu.com/SoftwareUpdates#pausing-mobile>: "If you choose 'Pause' during a download or an app installation, the update should pause and return to its idle presentation (bug 1316933) ... Any later download — whether automatic or manual — should download the latest version, regardless of whether it is newer than the one already partially downloaded, but resuming the existing download if it is the same version."

Thanks for the report.

The current design [1] doesn't include that case indeed, assigning to mpt for input

Sorry, I don't understand this bug report. What is the functional difference between cancelling, and pausing and never resuming? I guess cancelling might mean the partial download is deleted. But I'd expect deleting partial downloads to be the sort of thing that is handled by cache control rather than requiring manual deletion.

That seems like a separate bug. It shouldn't matter whether you try to resume five seconds later or five weeks later; if the server implements HTTP Range:, resume should work.

On a pause it seems it would not check for newer updates when te user returns, which would seem more desirable rather than finishing an older update.

I agree the other symptom could be considered a different issue.

So the real problem is that resuming a download either doesn't, or seems like it doesn't, check for a newer version and download that instead?

If the problem is that it really doesn't, that's a bug in the code.

If the problem is that it doesn't seem to, that's fixed by the current design where there is never a "Resume" button. Choosing "Download" or "Update" should resume the existing download if that download happens to be the latest version. Specification updated. <https://wiki.ubuntu.com/SoftwareUpdates?action=diff&rev2=182&rev1=181>

is that still valid? could you describe what steps exactly you are taking and what should be different? is the issue for system image updates or click ones?

[Pat McGowan (pat-mcgowan)]

The current behavior seems to match the design, re-entering the app and the updates page resumes the download, no error is reported.
