The /tmp directory should have a minimum of 500 MB of space available.
Please check the disk space on /tmp.
If you can not increase disk space on /tmp, you can use following workaround:
# mkdir /ca_tmp
# chmod 777 /ca_tmp
# IATEMPDIR=/ca_tmp; export IATEMPDIR
Launch WCC installation again
After the installation is complete, remove the temporary directory /ca_tmp and unset the IATEMPDIR variable
# rm -rf /ca_tmp
# unset IATEMPDIR
Check if /tmp is not mounted as readonly. You can use following command to make /tmp non-readonly:
mount –o remount,exec /tmp
