dpkg: error processing package mailman (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
mailman
E: Sub-process /usr/bin/dpkg returned an error code (1)
我正在运行 Ubuntu 14.04.3。我的问题是:
什么原因造成这种情况?
更新: 根据@Ravan 下面的注释,我能够通过以下方式解决问题
cd /var/lib/dpkg/info/
rm mailman*
apt-get clean all
apt-get update
apt-get upgrade
虽然现在情况有所好转,但我仍然不知道是什么原因导致了这种情况。
答案1
删除所有文件后/var/lib/dpkg/info/
,很难说出问题是什么。
因此,如果你需要解释你的问题,就不要删除某些内容。或者阅读这,在做某事之前。
文件中发生错误/var/lib/dpkg/info/mailman.postinst
,这是该错误的错误消息:
子进程安装后安装脚本返回错误退出状态 1
这是有问题的代码或可以查找错误的地方。
for lang in ${site_languages}; do
printf "Installing site language ${lang} " >&2
mkdir -p ${mm_etc}/${lang}
for file in $(ls ${mm_dist}/${lang}); do
printf . >&2
langfile=${lang}/${file}
ucf --debconf-ok --three-way ${mm_dist}/${langfile} ${mm_etc}/${langfile} 2>/dev/null
done
printf " done.\n" >&2
done
不幸的是,无法确定更多情况。
