I have a Tryton instance that has been upgraded from 4.8 to 5.0, 5.2, …, 6.0 .  
When I open Sequences or Strict Sequences (“Nummernkreise” bzw. “Strikte Nummernkreise”) the folllowing error comes up:

    field = cls._fields[fname]
KeyError: 'groups'

```

With a completely new installed database, the error does not occur.  
It worked at the beginning of the year, so it may have been introduced with the update 5.8 to 6.0

What can I do?

It seems you have an access rule which read the groups fields which no longer exist.  
If you remove such rule it should work as expected.

Maybe it is some XML data that could not be updated by `trytond-admin`. So you probably need to force the update from the `Administration>Models>Models>Data`.

Thank you, it worked.  
There were unsynced entries in Administration\>Models\>Models\>Data.

After manually syncing each entry, I can open the Sequences mask again.
