"Unknown option 'caption'." error while installing VeraCrypt GUI on Linux

[TheDcoder]

Hello, I am trying to install VeraCrypt on to my Fedora computer but I got this error after clicking okay on the "Use veracrypt-uninstall.sh to uninstall" screen. Here is the output from my terminal:

[TheDcoder@localhost veracrypt-1.21-setup]$ ./veracrypt-1.21-setup-gui-x64
Verifying archive integrity...  100%   All good.
Uncompressing VeraCrypt 1.21 Installer  100%  
Warning: Missing charsets in String to FontSet conversion
Warning: Missing charsets in String to FontSet conversion
Warning: Missing charsets in String to FontSet conversion
Unknown option 'caption'.

I have no idea what option it is talking about, can anyone help me out? Thanks in Advance!
Edit: I forgot to mention that the console setup/installer went well, but I uninstalled it to install the GUI version.

Install "XTerm". VC setup need to open it.

GUI can be installed via "Run in terminal". For "Run" it need Xterm. It would be nice to have simple Readme in veracrypt-1.xy-setup.tar.bz2 which explains that.

I did not have success using this method. There was key difference for me. Here is what I did --

For me, there are two things I needed to do:
First run:
export LC_ALL=C

Then install xterm by keying
sudo dnf install xterm

Then re-run the install script VeraCrypt provides.

There is another tip out there stating to modify the /.bash profile file or something like this with the LC_All=C parameter. I have found that the install does not require this. Nor have I had any problems since install. So my opinion is to skip modifying the /.bash profile.
