Dear Maintainer,

it is currently impossible to install LMMS because of a broken
dependency.
apt complains about libgig10t64 being depended on by lmms, which is
not installable.

Solving dependencies... Error!
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
