The problem was caused by the following entry: > > - added the repo > echo deb [signed-by=/usr/share/keyrings/winehq-archive-keyring.gpg] > http://dl.winehq.org/wine-builds/debian/ bullseye main | tee > /etc/apt/sources.list.d/ winehq.list > The term "[signed-by=/usr/share/keyrings/winehq-archive-keyring.gpg]" is somehow not been used by debian and makes this problem. After deleting this entry, it worked perfectly. So the correct entry in /etc/apt/sourceslist.d/ winehq.list should be just this: deb http://dl.winehq.org/wine-builds/debian/ bullseye main Hope this helps others, too. Best regards Hans
