Ubuntu 21.04 环境安装 Citus 10.2 提示找不到对应软件包问题求助

报错核心原因 #

• 未提前添加Citus官方APT源，Ubuntu默认软件源不包含Citus安装包
• Ubuntu 21.04为非LTS版本，官方已停止维护，默认标准源已下线，需切换到旧源
• 缺少PostgreSQL官方源依赖，导致Citus包匹配失败

修复步骤 #

步骤1：切换Ubuntu 21.04 旧源 #

1. 备份原有源配置
   sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
2. 编辑源配置文件
   sudo nano /etc/apt/sources.list
3. 替换全部内容为旧源地址：

deb http://old-releases.ubuntu.com/ubuntu/ hirsute main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ hirsute-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ hirsute-backports main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ hirsute-security main restricted universe multiverse

4. 保存退出后更新源
   sudo apt update

步骤2：添加PostgreSQL官方源 #

sudo apt install -y curl ca-certificates
curl https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/postgresql.gpg
echo "deb http://apt.postgresql.org/pub/repos/apt/ hirsute-pgdg main" | sudo tee /etc/apt/sources.list.d/pgdg.list
sudo apt update

步骤3：添加Citus官方源 #

curl https://install.citusdata.com/community/GPG-KEY-CITUS | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/citusdata.gpg
echo "deb https://install.citusdata.com/community/deb/ hirsute main" | sudo tee /etc/apt/sources.list.d/citusdata.list
sudo apt update

步骤4：执行安装 #

sudo apt-get -y install postgresql-14-citus-10.2

备选方案（源无匹配包时使用） #

采用源码编译方式安装：

1. 安装编译依赖
   sudo apt install -y postgresql-server-dev-14 make gcc git
2. 拉取Citus 10.2版本源码并编译安装

git clone --branch v10.2 https://github.com/citusdata/citus.git
cd citus
./configure
make
sudo make install
