Requesting for drivers for UGEE'S G5

Not working with Krita.Can be detected by GIMP but cannot load stylus’s pressure and x-y coordinates.
Having tried to install digimend,but failed.

aster@Aster:~/下载/digimend-kernel-drivers-6> make -f Makefile
make -C /lib/modules/4.4.70-18.9-default/build SUBDIRS=/home/aster/下载/digimend-kernel-drivers-6 modules
make[1]: *** /lib/modules/4.4.70-18.9-default/build: 没有那个文件或目录。 停止。
Makefile:9: recipe for target 'modules' failed
make: *** [modules] Error 2

Unable to make digimend.I guess it has something to do with snapper rollback,as the Linux kernel I now use is 4.4.27-2.I have talked in IRC but not solved.
Special thanks for IRC user Mirppc_
