Hi,
Thank you for posting in Symantec community.
The SEP Linux client requires 32-bit Linux libraries.
On Ubuntu or Debian Linux distros:
sudo apt-get install ia32-libs
# "Package ia32-libs (32-bit libraries) no longer available"? Use the following command on newer versions of Ubuntu/Debian:
sudo apt-get install libc6:i386 libX11-6:i386 libncurses5:i386 libstdc++6:i386
On Red Hat base Linux distros (RHEL, CentOS, Scientific Linux):
sudo yum install glibc.i686 libgcc.i686 libX11.i686
