Update problem GrandOrgue on Debian 10

    Hello all,

    I use GrandOrgue on linux Debian 10.

    Since a few days I have problems with updating packages. When I try to reinstall the key, this is what I get:

    Code
    $ sudo wget -nv https://download.opensuse.org/repositories/home:e9925248:grandorgue/Debian_10/Release.key -O "/etc/apt/trusted.gpg.d/home:e9925248:grandorgue.asc"

$ sudo apt-get update
...

The following signatures were invalid: EXPKEYSIG 3536C1B64FC39E69 home:e9925248 OBS Project <home:e9925248@build.opensuse.org>

    Maybe the release key is out of date.

    Best regards,

    Marcel
