Hello @meghana_tulla!

Older versions of UCX may fail to install because they try to create legacy dashboards, which are no longer supported following the April 7 update. To work around this, make sure your Databricks environment is aligned with the latest UCX requirements.
You can try upgrading to latest UCX version v0.58.0, as it includes the most recent fixes and improvements. If you're still running into issues, consider using a slightly earlier version instead of the latest one, it might offer better compatibility depending on your setup.
