Error when copying files from one location to another: OC\ServerNotAvailableException: Legacy cipher is no longer supported!

Steps to reproduce

copy any file from one location/folder to another.

Expected behavior

previous to updating from NC 23.0.3 to 23.0.4 there would be a resemblance of the file but it wouldn't open, and when downloaded also wouldn't open. In NC 23.0.4 I just get an error and nothing happens. logs pasted below.

Did you read https://docs.nextcloud.com/server/23/admin_manual/configuration_files/encryption_migration.html ?

[szaimen]

Hi, please update to 24.0.8 or better 25.0.2 and report back if it fixes the issue. Thank you!

Hi, please update to 24.0.8 or better 25.0.2 and report back if it fixes the issue. Thank you!

I have this error too appearing im my NC logs.
Nextcloud 25.0.2.3
PHP 8.0.27
MariaDB 10.6.11

[joshtrichards]

Please run:

occ encryption:scan:legacy-format

If you have some entries, you may need to add the following to your configuration for the time being:

'encryption.legacy_format_support' => true

IMO this is mostly a documentation matter (i.e. see nextcloud/server#22478) following nextcloud/server#22218 (also relevant: nextcloud/server#27501). It's mostly in the docs, but could probably use some clarity.

Getting this on a brand new server with encryption disabled but using SSE-C.
