error: Failed dependencies

rpm -Uvh erlang-23.3.1-1.el7.x86_64.rpm warning: erlang-23.3.1-1.el7.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 6026dfca: NOKEY error: Failed dependencies: erlang(x86-64) = R16B-03.18.el7 is needed by (installed) erlang-examples-R16B-03.18.el7.x86_64

zero dependencies?

I will convert this issue to a GitHub discussion. Currently GitHub will automatically close and lock the issue even though your question will be transferred and responded to elsewhere. This is to let you know that we do not intend to ignore this but this is how the current GitHub conversion mechanism makes it seem for the users :(

I do not appreciate the sarcasm. This package has no dependencies other than an implicit one on modern OpenSSL. You can check it yourself.

key ID 6026dfca: NOKEY

is the line you are looking for.

error: Failed dependencies:
erlang(x86-64) = R16B-03.18.el7 is needed by (installed) erlang-examples-R16B-03.18.el7.x86_64

has nothing to do with this package. Something named erlang-examples-R16B-03.18.el7.x86_64 is missing a dependency (and R16B03 is an Erlang version from many years ago).

So while you haven't provided any details as to what exactly has been done, my best guess is that you did not import the signing key and thus yum refused to install this package. It would not satisfy the dependency below anyway, however, since you try to install Erlang 23.3 and the "examples" one needs R16B03 which is a version from 2014:

I don't mean to be sarcastic，sorry My commands ： wget https://github.com/rabbitmq/erlang-rpm/releases/download/v23.3.1/erlang-23.31-1.el7.x86_64.rpm ->download has been done -> rpm -Uvh erlang-23.3.1-1.el7.x86_64.rpm -> The above warning has come up

@hhhChan OK, perhaps I misread your post. You need to import the signing key first. There may be unresolved dependencies in the yum database.

The following succeeds for me using the centos:7 Docker image:

yum update -y

rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
curl -sLO https://github.com/rabbitmq/erlang-rpm/releases/download/v23.3.2/erlang-23.3.2-1.el7.x86_64.rpm
yum install ./erlang-23.3.2-1.el7.x86_64.rpm

The output to confirm:

Perhaps removing the package with the unmet dependency as well as any existing erlang packages installed would help:

yum remove -y erlang erlang-examples

Something like that.

I could not find erlang-examples in the standard Yum repositories, though.
