Hi all, Debian sid，想要upgrade，但是在安装开始，出现如下问题： Setting up tzdata (2007f-4) ... /var/lib/dpkg/info/tzdata.postinst: line 28: /etc/timezone: Permission denied dpkg: error processing tzdata (--configure): subprocess post-installation script returned error exit status 1 Errors were encountered while processing: tzdata E: Sub-process /usr/bin/dpkg returned an error code (1) Google没有什么结果，这个问题如何解决？ -- Best regards, Huisi
