Error:
 Problem: problem with installed package
corosync-3.0.2-3.el8_1.1.x86_64
  - package corosync-3.0.2-3.el8_1.1.x86_64 requires
corosynclib(x86-64) = 3.0.2-3.el8_1.1, but none of the
providers can be installed
  - cannot install both corosynclib-3.0.3-2.el8.x86_64 and
corosynclib-3.0.2-3.el8_1.1.x86_64
  - cannot install the best update candidate for package
corosynclib-3.0.2-3.el8_1.1.x86_64
(try to add '--allowerasing' to command line to replace
conflicting packages or '--skip-broken' to skip
uninstallable packages or '--nobest' to use not only best
candidate packages)
