I keep getting this error whenever I tried installing. Not exactly sure what this means or why. But I am able to at least assume it could be related to this particular bit of code:

File "/home/odoo/src/odoo/saas-16.4/addons/stock/models/stock_picking.py", line 286, in _check_sequence_code
    raise UserError(_("Sequences %s already exist.",
odoo.exceptions.UserError: Sequences Severina Services Inc Sequence in already exist.
