crash - dnf 因段错误而崩溃

Question

Fedora 4.10.8-200.fc25.i686+PAE

dnf 因“段错误(核心转储)”而崩溃。

我试图运行“dnf clean all”但没有成功。

运行“dnf upgrade”时，这会记录在 dnf.log 中:

这是在“消息”中记录的:

我可以做些什么来排除故障？

升级后遇到同样的问题

libdb-5.3.28-16 to libdb-5.3.28-24
libdb-utils-5.3.28-16 to libdb-utils-5.3.28-24

重建 rpm db 修复它

  % rm /var/lib/rpm/__db*
  % rpm --rebuilddb
