我按照这个网站安装了 RabbitMQhttps://attacomsian.com/blog/install-rabbitmq-macos-ubuntu

在安装 RabbitMq 的第 5 步，当我运行命令时出现此错误

当我运行 sudo apt update 时，显示此错误

    E: The repository 'http://www.rabbitmq.com/debian testing Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

请遵循官方文档： https://www.rabbitmq.com/install-debian.html#apt-quick-start-packagecloud

通过一个简单的脚本，您可以轻松地在 ubuntu 上安装 rabbitmq。

例如：

#!/usr/bin/sh

sudo apt-get install curl gnupg apt-transport-https -y

## Team RabbitMQ's main signing key
curl -1sLf "https://keys.openpgp.org/vks/v1/by-fingerprint/0A9AF2115F4687BD29803A206B73A36E6026DFCA" | sudo gpg --dearmor > /usr/share/keyrings/com.rabbitmq.team.gpg
## Launchpad PPA that provides modern Erlang releases
curl -1sLf "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0xf77f1eda57ebb1cc" | sudo gpg --dearmor > /usr/share/keyrings/net.launchpad.ppa.rabbitmq.erlang.gpg
## PackageCloud RabbitMQ repository
curl -1sLf "https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey" | sudo gpg --dearmor > /usr/share/keyrings/io.packagecloud.rabbitmq.gpg

## Add apt repositories maintained by Team RabbitMQ
sudo tee /etc/apt/sources.list.d/rabbitmq.list <<EOF
## Provides modern Erlang/OTP releases
##
## "focal" as distribution name should work for any reasonably recent Ubuntu or Debian release.
## See the release to distribution mapping table in RabbitMQ doc guides to learn more.
deb [signed-by=/usr/share/keyrings/net.launchpad.ppa.rabbitmq.erlang.gpg] http://ppa.launchpad.net/rabbitmq/rabbitmq-erlang/ubuntu focal main
deb-src [signed-by=/usr/share/keyrings/net.launchpad.ppa.rabbitmq.erlang.gpg] http://ppa.launchpad.net/rabbitmq/rabbitmq-erlang/ubuntu focal main

## Provides RabbitMQ
##
## "focal" as distribution name should work for any reasonably recent Ubuntu or Debian release.
## See the release to distribution mapping table in RabbitMQ doc guides to learn more.
deb [signed-by=/usr/share/keyrings/io.packagecloud.rabbitmq.gpg] https://packagecloud.io/rabbitmq/rabbitmq-server/ubuntu/ focal main
deb-src [signed-by=/usr/share/keyrings/io.packagecloud.rabbitmq.gpg] https://packagecloud.io/rabbitmq/rabbitmq-server/ubuntu/ focal main
EOF

## Update package indices
sudo apt-get update -y

## Install Erlang packages
sudo apt-get install -y erlang-base \
                        erlang-asn1 erlang-crypto erlang-eldap erlang-ftp erlang-inets \
                        erlang-mnesia erlang-os-mon erlang-parsetools erlang-public-key \
                        erlang-runtime-tools erlang-snmp erlang-ssl \
                        erlang-syntax-tools erlang-tftp erlang-tools erlang-xmerl

## Install rabbitmq-server and its dependencies
sudo apt-get install rabbitmq-server -y --fix-missing

和 ..

root@ubuntu-focal:/home/vagrant# rabbitmqctl status
Status of node rabbit@ubuntu-focal ...
Runtime

OS PID: 4038
OS: Linux
Uptime (seconds): 14
Is under maintenance?: false
RabbitMQ version: 3.9.4
Node name

答案2

发生这种情况是因为文件中的一个环境变量重新加载

/var/lib/dpkg/info/rabbitmq-server.postinst，

以下行：

. /etc/profile

您可以将其注释掉并执行以下操作：apt install --fix-broken -y
