Database upgrade for 5.24.0 hangs
Two of the four sites I tried to upgrade to CiviCRM 5.24.0 last night (from 5.23.3) failed and had to be rolled back. All four sites run on WordPress 5.4, PHP 7.3, Ubuntu 18.04 so I'm not sure why some succeeded and others failed. There's some difference in extensions but there are many permutations there and I haven't had time to go through them.
In each of the failure cases I deleted the /wp-content/plugins/civicrm folder and replaced it with the Civi 5.24.0 files and the I10n files. Then I deleted /wp-content/uploads/civicrm/templates_c, went to Administer > Administration Console > System Status and saw the expected red warning that a database update was needed. Clicked on that and saw the usual progress bar which got about half-way across and then stopped progressing. I came back about half an hour later and it was still hung, tried to refresh the page without success, went back to the status page and it said a database update was incomplete and to restore from a backup and try again. I did that, but the results were the same.
