I am attempting to install plugins since going to Yokohama but any hang at 1% background process.

Those tried at plugins: big and small and I restarted the Dev box many times.

Admin_Center_offline_OTNow_(DEV).store

Usage_Insights_Application_offline_OTNow_(DEV).store

DEv was the first upgrade to Yokohama and has been installed for a many weeks.

Note this is on-premise. But what log shows it I cannot see a failure in the portal??

Please log a now support case if it is client instance.

I have a case open about MetaSpaceMax error, for the same instance, the change they recommended seems like the environment is running a bit better, I'll try to install a plugin now also.

Maybe it's this known problem?

I'll make them as cancelled and restart services and retry;

How to resolve stuck plugin installation in ServiceNow - Support and Troubleshooting

[jeffreyluto]

I created a ticket with Support this is the steps they recommended:

Do not delete any data from the sys_mutex or sys_padlock tables without proper investigation.

Back up your instance before each step.

1. Clean up pending installations stuck at 0%.

• Go to sn_appclient_progress_tracker list.

• Search for state not equal to Success, Failed, or Cancelled.

• Mark the state as Failed or Cancelled.

1. Remove the mutex record blocking operations.

• Go to sys_mutex list.

• Search for the record with name update-mutex.

• Delete the record from the sys_mutex table.

1. Set stuck jobs to Cancelled in the execution tracker.

• Go to sys_execution_tracker list.

• Search for state not equal to Successful, Failed, or Cancelled.

• Set those jobs to Cancelled.

1. Remove padlock records blocking operations.

• Go to sys_padlock list.

• Delete all records.

1. Set stuck jobs to Cancelled in the progress worker list.

• Go to sys_progress_worker list.

• Search for state not equal to Complete or Cancelled.

• Set those jobs to Cancelled.

1. Verify the "App Operation Queue Health Monitor" job exists.

• Go to sys_trigger list.

• Search for name starting with App Operation Queue Health Monitor.

• If missing, import the XML file.
