Actually, I am not familiar with candi at all. I am using WSL on Windows 10 and the lib works perfectly until I have to install Trilinos (for step-17 and later use). Should I uninstall OpenMPI or MPICH instead? According to this link <https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fdealii%2Fcandi%2Ftree%2Fdealii-9.3%2Fdeal.II-toolchain%2Fpackages&data=04%7C01%7CWolfgang.Bangerth%40colostate.edu%7C9cb18e902b1743b8a69308d96fa53928%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637663577691305918%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=MVb3xqmP7AE0gx34gWKx%2FdVMZE7s1QKGcCKGIPqZsTg%3D&reserved=0>, I am not sure whether candi will help to install the lib with MPI or not since I do not see that on the list.

Yes, candi installs with MPI.

It would probably help to uninstall one of the two. Which one is maybe not that important. But, since WSL is really just an ubuntu system, you can also install deal.II via 'apt install dealii', I believe -- take a look at the Ubuntu installation instructions on our website!
