Module import failed for Notification Control

Hi all,
I have done migration from v10 to v11
Erpnext 11.1.28
Frappe 11.1.27

But when installing erpnext or migrating existing site the below error is shown:

Hello friend.

What have you tried so far?
I normally get such issues when moving to a new server and restoring sites before restoring the apps first.

  • Check your apps folder for existence of notification_control: ls apps
    ** In case you already have notification_control. You want to remove it and reinstall it: sudo rm -r apps/notification_control then bench get-app https://github.com/user/notification_control.git
  • Also check the content of sites/apps.txt: nano sites/apps.txt
  • I would probably reinstall all the dependent apps before the sites.

Edit:
On closer inspection it seems that’s got something to do with ERPNext. Try this:

  1. Reinstall ERPNext
  • Ensure your frappe and ERPNext are the same major version (10, 11 etc) with bench version
  • Remove ERPNext sudo rm -r apps/erpnext
  • Install ERPNext bench get-app https://github.com/frappe/erpnext.git
  • Install your sites
  1. Update bench
  • bench update --reset
  • Restore your customisations
  • Install and migrate your sites

Hi @adam26d,
Thanks for the support.
Actually missed bench update --reset now after doing so it fixed my problem.
Now on v11
