How to resolve error message: Undefined command: “debuginfo-install”. Try “help”. while debugging using GDB.

If you are debuggining any C program or any binary file, and faced similar error message below:

Temporary breakpoint 1, 0x08048427 in main ()
Missing separate debuginfos,

To resolve this issue, we need to install the missing glibc package corresponding to installed debuginfo.
