Invalid private key for encryption app. Please update your private key password in your personal settings to recover access to your encrypted files.

[stone212]

Steps to reproduce

This is complicated. I am migrating from nextcloud-snap.

1. Install Nextcloud as good as possible using the "instructions" here: https://docs.nextcloud.com/server/14/admin_manual/installation/source_installation.html#ubuntu-installation-label

2. Export Database from snap, import to new server, use this info in the wizard

3. Rsync contents of data folder

4. chown -R www-data:www-data /var/www/nextcloud/data

Expected behaviour

You log in and see your files with no error messags

Actual behaviour

You log in and you see this error:

Invalid private key for encryption app. Please update your private key password in your personal settings to recover access to your encrypted files.

I have tried the fixes in #8546 #8637 #5712

Confirming: seeing that on NC 15, Ubuntu 18.04.1, PHP 7.2

[abadiego]

I have the same issue

[stone212]

@abadiego Does it go away if you disable the Default Encryption module?

[abadiego]

I have NC 15, Ubuntu 18.04.1, PHP 7.2. Clean install

The problem goes away when disabling the Encryption module and comes back when enabling it.

[stone212]

@abadiego I am starting to think the Issue is that the module should not be "Default" enabled because you get this error if it is.

[abadiego]

@stone212 Do you mean to turn off encryption and problem solved?
How about removing Nextcloud and problem also solved!!

[abadiego]

I think I will install it with SNAP even if it's gonna take more resources

[Elfanar]

It was painful on my fresh installation, I finally fixed it by changing database value
run this sql query as qualified mysql user on nextcloud DB :

update oc_appconfig set configvalue = 'no' where appid = 'encryption' and configkey = 'enabled'

Problem will disappear but be careful if you have encrypted data.

[bloodyburger]

I have disabled both Default encryption and Server Side encryption but still get the error message. I use Nginx, Nextcloud 15.2 with PHP 7.1

[stone212]

I disabled Default Encryption (ignoring the warnings) and the error is gone. The warnings I realize are not a problem because I never used encryption. I like encryption but this server did not have it when I took over the migration.
