Package updates appear to vanish if download fails

[ThoricSolutions]

Short Description of the Bug
Our VIPM is connected to two private repos behind a VPN. I filtered the view to show "Upgrades" and five were listed, which had been identified a few days ago but I chose not to install them at that time. I selected all five and pressed the Upgrade button. The downloading process started but failed. This was because I'd forgotten to connect to the company VPN this morning, and hence the repos were not accessible. After all five failed to download they were removed from the list of available upgradable packages.

I've since reconnected to the VPN and the repos are visible / accessible once more, however VIPM doesn't show these upgrades anymore. If I change the filter from "Upgrades" to "Installed", then the five packages that were there previously are not listed, and another package that depends on them is showing a red exclamation icon suggesting those dependencies are completely missing.

Checking vi.lib I can see that VIPM uninstalled the old packages. Therefore, to see them in the list I have to switch filter to "All".

From a usability standpoint, uninstalling a package before confirming availability of a download is risky. I now have no package at all, I'd rather it left the out-of-date package untouched.

• VIPM Version and Build: 2020.1 (build 2348)
• Operating System Version: Win10 Pro (inside Hyper-V)
• LabVIEW Version: 2020 SP1 (32-bit)

Virtualization or Processor Version Information
Hyper-V, Lenovo ThinkPad Intel

Expected behavior
Do not uninstall the old packages before finishing the download of the new, so that the old package remains in the event of a download error.
