Try replacing the code /var/www/html/nextcloud/apps/libresign/lib/Migration/Version2040Date20211027183759.php by github code.

We need a new version of https://github.com/nextcloud/twofactor_gateway to finish the PR #801 and launch a new release of LibreSign with this bugfix.

I have replaced the /var/www/html/nextcloud/apps/libresign/lib/Migration/Version2040Date20211027183759.php file with the current version on git but am experiencing the same errors.

Same issue here.... I temporarily deinstalled libresign to get the update running through... just in case someone looks for a quick solution
within the container run
php occ app:remove libresign

or from host

docker run <nextcloudcontainer> php occ app:remove libresign

if an error about user and permission appears, the executing user needs to be the same as the file owner of the Nextcloud container and volumes (e.g. www-data)
in this case, figure out the username or id and use
docker run -u <name> <nextcloudcontainer> php occ app:remove libresign
or
docker run -u #<id> <nextcloudcontainer> php occ app:remove libresign

That said, this is all out of my memory... might be syntactically wrong, but it should give people an idea what to do.

LibreSign in latest version now have a more easy setup.

I recommend to use with server in version 25.
