I have fetched and installed all the dependencies that are required because I thought that might be the problem. But then too the following error is coming in the install process. Please improve the install process to completely support fedora. Below is the error :

I used apt install qemu to install QEMU separately and commented out the statement for installing QEMU in ./install.sh. Then the error did not recur. (WSL too)
(but unluckily another error happened in the following process. X_X
