Hi,

I have a KVM host running ubuntu 18.04 with libguestfs-tools version 1.36.13-1ubuntu3.3 installed from the Ubuntu's repo and when I try to use virt-cat for example on a VM it fails with:

libguestfs: error: appliance closed the connection unexpectedly.
libguestfs: error: guestfs_launch failed.

After doing "export LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1" and running the virt-cat command again I get:

guestfsd: error while loading shared libraries: libsbz.so: cannot open shared object file: No such file or directory

I've tried to reinstall libguestfs-tools with "apt-get --reinstall install libguestfs-tools", but I still get the same error. Can someone help me fix this?
