Wordpress installation aborting with strange Error

Hello,

after some testing and successful installation we have to uninstall the wordpress app because of some missconfiguration issues. Now, we want to install the wordpress app again but its aborting with the following error:
Unbenannt
How can I fix this?
Thank you very much!

Sebastian

How about doing what getting told?

Have a look at /var/log/univention/appcenter.log

/CV

Thank you. This it what the log is about:

Hi,

please remove (move) the directory “/var/lib/univention-appcenter/apps/wordpress/” and try to re-install the app.

Best regards
Felix

Thank you very much. But I have to tell you, that this was not a solution. The error message comes up again.

Best regards
Sebastian

OK, seems that there is something wrong with the Storage Driver, what is the ouput of

docker info

On my test system it is

Storage Driver: overlay2
Backing Filesystem: extfs
Supports d_type: true
Native Overlay Diff: true

Thank you! This is the output on my system:
