https://github.com/nextcloud/documentation/ is the repository for the documentation.

However the command name is correct

server/apps/encryption/lib/Command/ScanLegacyFormat.php

Lines 73 to 77 in adc0012

    
           protected function configure() { 
        
           	$this 
        
           		->setName('encryption:scan:legacy-format') 
        
           		->setDescription('Scan the files for the legacy format'); 
        
           }

but the command is only loaded if the encryption app is enabled. The warning is shown if encryption.legacy_format_support in your config.php is true. That's usually the case if the encryption app was enabled during the update and old key format use.

I guess if you enable the encryption app you can run the command. We should probably check if the app is enabled in the setup check.

cc @rullzer @MorrisJobke

I disabled the app I guess at some early 19.0.x (or even 18.0.x) state due to regular data loss. So this actually was not done by the update 19->20. However, I support the idea to consider whether he app is activated at all at this point.

Same here, my Encryption app is disabled since ages/versions ago (also was never used). I followed the yellow warning in admin page to docs, to the "unknown command" error, to this issue...

@danielb42

Same here, I never used encryption before and I started to get the warning after upgrading to v20 without possibility to scan my files because, as mentioned before, the module isn't enabled in my setup.
@danielb42 I just switched the legacy setting encryption in my config.php to false to get rid of the warning. Hope it helps

Same thing happens here on 20.0.3 after upgrading from 19.0.6. The documentation should be updated with a working how-to.

Also please update the documentation. I don't understand currently which kind of encryption is deprecated and if and how it potentially impacts me

I get this error in NC 21.

I enabled the encryption module and ran
occ encryption:scan:legacy-format
It said: "All scanned files are properly encrypted. You can disable the legacy compatibility mode."
I then disabled the encryption module app and the server still said:
"The old server-side-encryption format is enabled. We recommend disabling this. For more details see the documentation."

Then I ran
occ encryption:disable
It said "Encryption is already disabled"

So I don't know why the server still complains about it.

A friendly guy from a reddit forum has shown a way to get rid of the message: (https://www.reddit.com/r/NextCloud/comments/jyej7d/issue_with_occ_encryptionscanlegacyformat_command/)

make sure you are not using the legacy encrytion with: occ encryption:status
change the following parameter inside the config.php (should be in your nextcloud folder; e.g. /var/www/nextcloud/config/config.php) to false: 'encryption.legacy_format_support' => false,

Is this Issue still valid in NC21.0.3? If not, please close this issue. Thanks! :)

occ encryption:scan:legacy-format

Should be removed from the documentation, as the command is not longer available.

https://docs.nextcloud.com/server/22/admin_manual/configuration_files/encryption_migration.html

This issue is still here.
This page is wrong: https://docs.nextcloud.com/server/24/admin_manual/configuration_files/encryption_migration.html
the command occ encryption:scan:legacy-format does not work.
