Strange return on Verify Signature

I am trying to swap bisq from Windows to Linux Mint. First I had a problem because the Folder " Bisq" “btc_mainnet” was not created.
So I de-instaled bisq and now I try do do it right and verify the Signature bevor installing. Please see the Picture and tell me if it is verified now or not. The Name and the Fingerprint is ok but it says its no real hint that it is from the real owner.
Just realize, it is in german. Hope some one speaks it.
thanks Renate

I can attest this issue was solved over telegram, this install was done from an external repository so data directory was not being created, or not in the right place. Installing from official package resolved the issue
