The "addressfield_linear" plugin does not exist.

From a quick search it looks like the linear formatter was provided by https://www.drupal.org/project/addressfield_tokens → , and now your system is complaining that it doesn't exist on the D8 side.

We do have migration plugins for addressfield, defined here:
https://git.drupalcode.org/project/address/-/blob/2.1.x/src/Plugin/migra...
https://git.drupalcode.org/project/address/-/blob/2.1.x/src/Plugin/migra...
but I don't know what the right workaround here would be. I guess you need to reset the used formatter during the migration?

You mean "unconfigure" or reconfigure the current field formater in D7 before migration? I think this is technically not possible. All fields are greyed out or the dropdowns have just one option. Nothing I can change or at least I have no clue how and where. Maybe you can shed some light to me, please?

Normaly the module should have a migration of old formater to new formater name. Never coded it, but this is the way how it should work for a smooth migration. I have no idea what gets broken here with this error.

Right. Unfortunately, I don't see what we can do on our end, since it's not our formatter (nor addressfield's).

If you end up solving it, please share here.

Thanks for note that it may come from Addressfield Tokens module. As it was complaing against addressfield i tought it is targeted there. I try to find out where I used such tokens... cannot remember it.
