ERROR 127 can't debug on Linux Debian

In clion (c++) on Debian Linux when I want to debug I get this message:

During startup program exited with code 127.

Process finished with exit code 0

ERROR 127 means that debugger cant be found. Googling didn't help me. How can I fix that in CLion? Debian Linux.(GDB 7.8)
