SNX install script workaround in Ubuntu 24

Hello, everyone.

Here's a fix for an SNX client installation issue on Ubuntu 24.04.

The installer couldn't find libstdc++6. It searches /usr/lib/, but on 64-bit Ubuntu, the library is elsewhere. This path mismatch breaks the installation, but the browser window raises no warnings.

I created a symbolic link using:

sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.33 /usr/lib/libstdc++.so.6

This workaround links the expected path to the actual library location.

Details:

- OS release: Ubuntu Desktop "24.04.2 LTS (Noble Numbat)"

- Related library: libstdc++6 (GNU Standard C++ Library v3)

- Library paths (mostly symbolic; the last one is the actual path):

/usr/libx32/libstdc++.so.6.0.33 /usr/lib/i386-linux-gnu/libstdc++.so.6.0.33 /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.33 /usr/lib32/libstdc++.so.6.0.33 /usr/x86_64-linux-gnu/lib/libstdc++.so.6.0.33

- Pattern mismatch:

/usr/lib/libstdc++*

- Code snippet from the failing snx_install.sh script (line 63):

# link the stdc++ library STDCPLUSPLUS=`ls /usr/lib/libstdc++* | grep so | head -n 1` > /dev/null 2>&1 if [ "${STDCPLUSPLUS}" != "" ] then COMMAND_TO_RUN="ln -sf ${STDCPLUSPLUS} /usr/lib/libcpc++-libc6.1-2.so.3; ${COMMAND_TO_RUN}" fi

Solution:

1. Create the symbolic link:

sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /usr/lib/libstdc++.so.6

2. Run the installer:

sudo bash snx_install.sh

Notes:

- This script contains a binary blob at the end, so I don't recommend editing it unless you know the ropes.

- Your actual library location may vary, but the path should be similar - double-check before linking.

How can we download snx_install.sh ? Can you share link ? The old version is not working for me 😞 I mean this link : https://support.checkpoint.com/results/download/22824. It gives "snx: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory". I tried so much way but I couldn't get 😞

Thanks.

@mahmut4242 The link actually works if you are already logged into your UserCenter account, although it might be a function of software subscription as well.

For more details and a proper download link, see this: https://support.checkpoint.com/results/sk/sk90240

https://support.checkpoint.com/results/sk/sk90240 isn't coming up for me.

I was successful with one install and snx_install.sh on a different ubuntu box and with this https://support.checkpoint.com/results/download/22824 I'm testing it now.

I ended up geting this working by just using the sslvpn portal. I did have to install Java and other libraries. sk119772 was helpfule. It's nice Check Point provides snx_install.sh and cshell right there on the portal. I was looking all over the webs for those files and sk22824 reference to snx_install_linux30.sh was throwing me off, The snx_install.sh was on the sslvpn portal the whole time!
