Cause
On Red Hat 8 and above, the libncurses.so.5 binary is not available by default.
Following are the dependent library versions available according to platforms.
RHEL 7 has libncurses.so.5 as default library.
RHEL 8 has libncurses.so.6.1 as the default library (However, libncurses.so.5 is also available for download from the Red Hat Repository.)
RHEL 9 has libncurses.so.6.2 as the default.
Resolution
On RHEL 8.x and above, search for the existing binary libncurses.so.6.x and libtinfo.so.6.x as part of ncurses-libs-6.x RPM package and create a soft link as shown below.
For RHEL 8.x use this option:
ln -s "/usr/lib64/libncurses.so.6.1" "/usr/lib64/libncurses.so.5" ln -s "/usr/lib64/libtinfo.so.6.1" "/usr/lib64/libtinfo.so.5"
For RHEL 9.x use this option:
ln -s "/usr/lib64/libncurses.so.6.2 "/usr/lib64/libncurses.so.5" ln -s "/usr/lib64/libtinfo.so.6.2" "/usr/lib64/libtinfo.so.5"
