Unable to install Sophos on my Oracle Linux 8 system.

I am new to Sophos, but I have successfully in stalled Sophos on other systems with no issues. On this one system when I run the SophosInstall.sh script I get the following error: 

# ./SophosInstall.sh
Installing Sophos Anti-Virus for Linux with arguments: []
Downloading medium installer
installer/bin64/installer: error while loading shared libraries: libSUL.so.0: cannot open shared object file: No such file or directory
Failed to download the medium installer! (Error code = 127)

I am running this from root, the /tmp dir does not have noexec. Not sure what else to check. Thanks for the assist.

  • No, same error that didn't help.

    # ./SophosInstall.sh --autostart=False
    Installing Sophos Anti-Virus for Linux with arguments: [--autostart=False]

  • In some cases where CIS Level 1 hardening is enabled, this can cause issues with the installation. Could you try disabling this temporarily? 

    Another option would be to make changes to "fapolicyd" to reduce restrictions on the device. 

    If this still does not work, it may be best to open a support case so our team can look into this issue further. Please send me a PM with the case ID so I may add some notes to the case as well if you choose to go this route.

  • It is the CIS hardening that is causing the issue. Once I remove it all then I can install Sophos just fine. Not exactly sure what exact setting kill the install but I'll figure that out in time. Thanks for the assist. 

  • I can confirm my RHEL9 installations with 800-171 security hardening also output the same "libSUL.so.0: cannot open shared object file: No such file or directory" message and Error code 127... 

    The RHEL hardening stigs are hitting this sh script from two sides
    1. noexec /tmp 
    2. fapolicyd

    # mkdir -p /opt/sophos_tmp && chmod 777 /opt/sophos_tmp
    # export TMPDIR=/opt/sophos_tmp/ && ./SophosSetup.sh

    I'm not sure what you're going to do here to address this.


    Anyway, good luck!
