unknown group 'ssl-cert' in statoverride file
dpkg: unrecoverable fatal error, aborting: syntax error: unknown group ‘ssl-cert’ in statoverride file E: Sub-process /usr/bin/dpkg returned an error code (2) A package failed to install. Trying to recover: 安装vsftpd时出现了上面的错误提示，整了半天也不知道从哪里下手。最后还是解决了，我也不知道是怎么回事，记录一下以后参考 # addgroup –system ‘ssl-cert’ 这样就创建了一个SSL-CERT组，然后安装aptitude install ssl-cert 再安装aptitude install vsftpd
