Had issues where QEMU packages were not in sync and got an error:
... Note: only modules from the same build can be loaded. ...
The qemu package no longer lists dependencies on qemu-system, qemu-user,
qemu-utils in apt show.
Qemu-utils is recommended by other packages but I am unsure as to whether
this will guarantee an upgrade in all circumstances.
While qemu-system does list dependencies on the arm, mips, ppc... packages
they are unversioned and therefore do not keep in step.
