Breaks Nextcloud 21

[agross]

I just upgraded to Nextcloud 21. With Yubikey enabled users cannot use the web UI (sync clients still work).

This the logged (formatted):

It looks like something has changed in the way a plugin needs to register with the autoloader. I'm gonna have to take some time to figure out how to make it work in version 21.

Any update to this?

Same problem here.
Was able to disable the plugin using command line occ on the server; but note that if that is the only two factor module that's enabled and 2fa is required to log in, you will be locked out of nextcloud.

sudo -u www-data php occ app:disable twofactor_yubikey

(see the manual for more info about how to run the occ)

Is there any news about this issue. @jaark

[rleo79]

Any news about this issue ?
Just got a 12 hours of downtime on a production installation due to twofactor_yubikey enabled and snap installed automatically NC21 !
