I did a lot and have the feeling to be almost there but I need help to understand this error message and have a solution to it:
Executing frappe.patches.v6_2.rename_backup_manager in site2.local (a46003081c220c38)
/home/frappe/frappe-bench/apps/frappe/frappe/integrations/doctype/dropbox_backup/dropbox_backup.json missing
ImportError: Module import failed for Dropbox Backup (frappe.core.doctype.dropbox_backup.dropbox_backup)
I see dropbox_settings and dropbox_settings.json. I installed again dropbox_backup but the patch seems not to rename it…I would appreciate.
