OK, got it all fixed -- but I have no idea what caused this to happen. Here's what I found and what I did to correct it.
When I first checked, the provider for all of the packages except for UpgradeMODX was set to "1". UpgradeMODX was set to "3". So I set all the others to "3", deleted the contents of /core/cache, and logged in.
That fixed about half of them. Some showed "modx.com" as the provider and worked properly; others showed a blank provider and returned the error message.
So I went back into the DB and looked in the next table, keepintune_transport_providers. It contained just one row. Everything looked perfect -- except that the id was set to "3". So I reset it to "1", then returned to the keepintune_transport_packages table and reset all of the providers to "1", dumped the cache, and logged in.
Perfect! All the packages now show "modx.com" as their provider and all of their update buttons work normally.
Thanks, Bob, for pointing me in the right direction.
