Package: libsane-extras
Version: 1.0.22.3
Severity: grave

Hello,
when installing gnome, libsane-extras fails to install due to:

Unpacking libsane-extras:amd64 (from .../libsane-extras_1.0.22.3_amd64.deb) ...
dpkg: error processing /var/cache/apt/archives/libsane-extras_1.0.22.3_amd64.deb (--unpack):
 trying to overwrite shared '/etc/sane.d/dll.d/libsane-extras', which is different from other instances of package libsane-extras:amd64

Regards,
Sandro
