`sudo yum update` 抛出 Requires ... Removing ... Obsoleted By

如何解决`sudo yum update` 抛出 Requires ... Removing ... Obsoleted By

我在 Amazon Linux 机器上：

.navbar-community-menu:after {
  transition: opacity 0.2s;
  content: "";
  width: 24px;
  height: 24px;
  display: flex;
  background-image: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 24 24' fill='white' width='24px' height='24px'%3E%3Cpath d='M0 0h24v24H0z' fill='none'/%3E%3Cpath d='M20 2H4c-1.1 0-1.99.9-1.99 2L2 22l4-4h14c1.1 0 2-.9 2-2V4c0-1.1-.9-2-2-2zM6 9h12v2H6V9zm8 5H6v-2h8v2zm4-6H6V6h12v2z'/%3E%3C/svg%3E");
  background-repeat: no-repeat;
  background-position: center;
  margin-right: 12px;
}

.navbar-community-menu:hover:after {
  opacity: 0.5;
}

.navbar-community-menu:after,.navbar-community-link:after {
  border-style: none !important;
  margin-left: -5px !important;
}

当我尝试 # this command returns Amazon Linux AMI release 2018.03 cat /etc/system-release 时，我得到 this output。我不能在 SO 上发布完整的输出，但这里是爆炸的部分：

sudo yum update

解决方法

啊哈，我需要：

sudo yum remove epel-release
sudo yum update
