Comment (by peterwilsoncc):

 That's correct, no errors are logged during the update process. Until
 reactivation, success is reported for each step for the plugins that
 fatal/are incomplete.

 By slug:

 * `woocommerce`, `gutenberg`, `wpforms-lite`: fatal errors logged upon
 reactivation attempt only. Source is the plugin's `require` of files.
 * `akisment`: warnings logged upon reactivation and subsequent page loads
 (due to the use of `include` rather than `require`, the update is
 incomplete)
 * `jetpack`, `wordpress-seo`, `mailpoet`: plugin's error handling
 gracefully recovers, showing admin notice
