Trying other mirror.
One of the configured repositories failed (Apache Cassandra),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=cassandra ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable cassandra
or
subscription-manager repos --disable=cassandra
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=cassandra.skip_if_unavailable=true
sh-4.2$ sudo rpm --import https://downloads.apache.org/cassandra/KEYS
error: https://downloads.apache.org/cassandra/KEYS: key 15 import failed.
将GPGKEY任为新URL，但同样的错误也失败了：
sh-4.2$ sudo rpm --import https://downloads.apache.org/cassandra/KEYS
error: https://downloads.apache.org/cassandra/KEYS: key 15 import failed.
sh-4.2$ sudo curl -I https://archive.apache.org/dist/cassandra/redhat/311x/

从我能告诉的是，Amazon Linux 2（AL2）是基于10年以上的Red Hat Enterprise Linux 7（RHEL）（全面支持，于2019年结束了，
雷格在2024年的维护结束了）。 Al2运行旧版本的rpm：
$ rpm --version
RPM version 4.11.3
