qemu-system-* not installable in ascii
apt-get install qemu-system-x86 fails due to the following unmet dependencies:
The following packages have unmet dependencies: qemu-system-x86 : Depends: libiscsi2 (>= 1.10.0) but it is not installable Depends: libpng12-0 (>= 1.2.13-4) but it is not installable Depends: libxen-4.4 (>= 4.4.1) but it is not installable
It seems that the package has been forked from Debian and maintained in-house by Devuan? I also tried to apt-build it after modifying the contol file to use the versions of libpng, libxen, etc. available on ascii, but without success, due to an issue related with xfs support.
