Hi , Thanks for your quick response.
This is not an issue from core-utils as you mentioned. I found the fix for this issue , i have copied the terminfo database file of the xterm editor to the /usr/share/terminfo of the chroot directory , it is working fine now. ncurses libraries are expecting the terminal database files. Thanks, Rajesh Dasari.
