we have severe trouble bringing up again all files on our owncloud server.
We've enabled encryption and set a master password - although maybe too late as I cannot decrypt all files as admin.
One User shared 3-4 GBs in a lot of files with many others by link or by name and set specific rights for editing etc.
Than suddenly the problems appeared and users were not able to open/decrypt files anymore. It seems to me, that those users haven't been logged in before on the website but used only the desktop client or a share-link to see the files.
Anyway - due to the complexity we decided to disable encryption but - the admin wasn't able to decrypt all files! Even user by user with each users-password did not work properly as the app was deactivated during decrytion on the command line by typing sudo -u apache php occ encryption:decrypt --all [USER]
Long story short... How could I (as admin) possibly gain again access to all files and decrypt them on the shell - without the occ encryption command?
User passwords can be retrieved and shouldn't be an issue.
