dpkg: unrecoverable fatal error, aborting:
unknown system group 'smmsp' in statoverride file; the system group got removed
before the override, which is most probably a packaging bug, to recover you
can remove the override manually with dpkg-statoverride
E: Sub-process /usr/bin/dpkg returned an error code (2)
有人可以解释一下这个问题吗？
答案1
我得到了答案http://rickfoosusa.blogspot.com/2012/04/howto-ubuntu-unknown-user-in.html
当我输入
$ grep 'smmsp' /var/lib/dpkg/statoverride
我懂了
root smmsp 2755 /usr/lib/sm.bin/sendmail
所以我使用sed如下方法删除了它
$ sudo sed -i '/smmsp/d' /var/lib/dpkg/statoverride
现在$ sudo apt-get upgrade运行完美。
