Debian:安装exim4。‘’Debian exim‘不是有效的组名

Question

我正在尝试安装exim4，下面是命令sudo apt-get install exim4的输出

第一个故障是'Debian-exim' is not a valid group name

在脚本/var/lib/dpkg/info/exim4-config.postinst中，我找到了引发错误的命令：

adduser --system --group --quiet --home /var/spool/exim4 --no-create-home --disabled-login --force-badname Debian-exim

此命令的输出为

groupadd: 'Debian-exim' is not a valid group name
adduser: `/usr/sbin/groupadd -g 115 Debian-exim' returned error code 3. Exiting.

在此之前，我能够在三台机器上安装Exim4。现在我觉得我做的一切都是一样的。

我不知道为什么大写字符的组不想使用选项--force-badname创建。

如何解决这个问题，创建这个系统组？

Debian GNU/Linux 8.8 (jessie)

更新

我假设命令adduser --group在groupadd上工作，它不支持选项--force-badname。但我还是不知道该怎么办。

Answer 1

我在安装backuppc时遇到了同样的问题。

我在上面的命令中用adduser替换了addgroup，并创建了Debain组名。之后，安装成功了。

addgroup --system --group --quiet --home /var/spool/exim4 --no-create-home --disabled-login --force-badname Debian-exim

备注：

1. 我没有检查参数是否适合addgroup，但没有得到一个错误
2. 我还删除了--quiet参数，这样我就可以看到发生了什么
