i would have the system administrator run
zypper in fuse fuse-devel
or do you also need "gvfs-fuse " or "zfs-fuse"
FUSE is installed on this system but its libraries are not
"libfuse2" is required by gvfs-fuse
odd it should be installed
zypper in gvfs-fuse libfuse2
from your error
/usr/bin/install: cannot remove `/sbin/mount.fuse': Permission denied
if you do not have root permission you can NOT remove a system file
have the System Admin. do that.
