Edit: As per the response I received over at the GNS3 forums, looks like the IOU binary is 32-bit and therefore require 32-bit libraries.

I'm not sure if this is the appropriate place to ask but I hope someone here has some insight. I'm working on getting L2 IOU images up and running in GNS3 and I'm stuck at an issue. This is on a Ubuntu 16.04 machine. The images won't run because it says it's missing dependencies, specifically libcrypto.so.4.

I found this video that was supposed to be remedy however it wasn't based on Ubuntu. Following that, I issued the following commands to try and fix it.

tinyrick@tinyrick-PC:~$ find / -name 'libcrypto' 2> /dev/null



tinyrick@tinyrick-PC:~$ sudo ln -s /lib/x86_64-linux-gnu/libcrypto.so.1.0.0 /lib/libcrypto.so.4

[sudo] password for tinyrick:

tinyrick@tinyrick-PC:~$ sudo ln -s /usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0 /usr/lib/libcrypto.so.4

[sudo] password for tinyrick:


The video had used the /usr/ base directory so I tried that after leaving it out failed me.

In contiunation, I have removed both symbolic links to try and tried to use another suggested command to find the dependency. The following is the output of such....

tinyrick@tinyrick-PC:~$ sudo rm /usr/lib/libcrypto.so.4
[sudo] password for tinyrick:

tinyrick@tinyrick-PC:~$ sudo rm /lib/libcrypto.so.4

tinyrick@tinyrick-PC:~$ whereis libcrypto.so.4



Any suggestions?


You have to use the 32bit version of the library, if you have a 64bit system this wont be downloaded.

To download the 32bit version go to https://www.codeweavers.com/support/wiki/diag/missinglibssl

Then you can create a symbolic link using:

find / -name '*libcrypto*' 2> /dev/null

Look for something like:


Then create the link:

sudo ln -s /lib/i386-linux-gnu/libcrypto.so.1.0.0 /usr/lib/libcrypto.so.4
