Error: 
 Problem: package gdb-8.3.50.20190610-16.0.riscv64.fc31.riscv64 requires gdb-headless(riscv-64) = 8.3.50.20190610-16.0.riscv64.fc31, but none of the providers can be installed
  - package gdb-headless-8.3.50.20190610-16.0.riscv64.fc31.riscv64 requires libsource-highlight.so.4()(64bit), but none of the providers can be installed
  - conflicting requests
  - nothing provides libboost_regex.so.1.66.0()(64bit) needed by source-highlight-3.1.8-23.0.riscv64.fc30.riscv64
