Error: Error downloading packages:
  Cannot download VirtualBox-6.1-6.1.4_136177_fedora31-1.x86_64.rpm: All mirrors were tried

Obviously packages are broken or checksum was calculated wrong.

Due to security reasons this update was rejected by package manager.

As seen in ​https://forums.virtualbox.org/viewtopic.php?f=7&t=96941&p=470426#p470426, it also happens with Centos 7.7, Centos 8, Fedora 30 and Fedora 31 (but not, for instance, with Fedora 29).
