无法创建目标集群9.6

我在Ubuntu 16.04，并安装的Postgres上9.5无法创建目标集群9.6

然后我对9.5升级的Postgres 9.6，和我在postgresql offical download page安装9.6：

然后我跑apt install postgresql-9.6，安装后，我运行下面的命令来升级

# stop the 9.6 
$ sudo pg_dropcluster 9.6 main --stop 

# upgrade 9.5 to latest version 
$ sudo pg_upgradecluster 9.5 main 

sudo pg_upgradecluster 9.5 main 
Stopping old cluster...

perl: warning: Setting locale failed. 
perl: warning: Please check that your locale settings: 
    LANGUAGE = "en_US:en", 
    LC_ALL = (unset), 
    LC_CTYPE = "UTF-8", 
    LANG = "en_US.UTF-8" 
    are supported and installed on your system. 
perl: warning: Falling back to a fallback locale ("en_US.UTF-8"). 
Error: The locale requested by the environment is invalid. 
Error: Could not create target cluster

钍en我试图使用psql命令来连接旧集群。但错误：

$ psql -U postgres -h localhost 
psql: FATAL: no pg_hba.conf entry for host "::1", user "postgres", database "postgres", SSL on 
FATAL: no pg_hba.conf entry for host "::1", user "postgres", database "postgres", SSL off

似乎pg_hba.conf的是错的，然后我在/etc/postgresql/9.5/main/pg_hba.conf检查pg_hba.conf的，但它似乎很动听：

local all    postgres        peer

如pg_upgradecluster所述：perl：warning：设置区域设置失败。 perl的：警告：请检查您的区域设置： LANGUAGE = “EN_US：恩”， LC_ALL =（未设置）， LC_CTYPE = “UTF-8”， LANG = “是en_US.UTF-8” 支持并安装在您的系统上。 perl：警告：回退到回退区域设置（“en_US.UTF-8”）。错误：环境请求的语言环境无效。错误：无法创建目标群集 –

解决方案是？ – Calin

的解决方案是一个简单的在你的终端运行以下命令：

$ sudo locale-gen "en_US:en" 
$ sudo locale-gen "en_US.UTF-8"
