MATLAB: Error while installing MATLAB R2020a on Fedora 32

fedoralinuxr2020a

When I try to install MATLAB R2020a on Fedora 32, I get the following error: 
terminate called after throwing an instance of 'std::runtime_error'
  what():  Unable to launch the MATLABWindow application
Aborted
If I go to ./bin/glnxa64/ and try to execute MATLABWindow:
./MATLABWindow: symbol lookup error: /lib64/libk5crypto.so.3: undefined symbol: EVP_KDF_ctrl, version OPENSSL_1_1_1b
libk5crypto.so.3 is installed, so that does not cause the problem. What else could it be?

Best Answer

The MATLAB 2020a installer contains its own shared library libcrypto.so.1.1, but uses the system library libk5crypto.so.3. System library libk5crypto.so.3 uses new symbols, which system library libcrypto.so.1.1 has, but MATLAB's library libcrypto.so.1.1 doesn't. So, you have to delete the MATLAB installer's copy of libcrypto.so.1.1. The sequence of commands that worked for me in RHEL 8.2 were:
cd /home/YourUserName/Downloads/matlab_R2020a_glnxa64/bin/glnxa64
rm libcrypto.so.1.1
sudo su -
cd /home/YourUserName/Downloads/matlab_R2020a_glnxa64
export DISPLAY=':0'
./install
That got the installer to work.
P.S. -- When I got to the step of entering my MathWorks account password in the resulting MATLABWindow application, the password field wouldn't let me type until I selected "Show Details" from the "MathWorks Product Installer" drop-down menu in the top menu bar and then clicked back into the main screen of the MATLABWindow application. Basically, I think I had to remove and restore focus on the MATLABWindow application main screen to get the password field working again.
P.P.S. -- Thanks to Petr at https://bugzilla.redhat.com/show_bug.cgi?id=1829790 for pointing me in the right direction on this.
