如题,升级系统时怎么老是出现
Reading Package Lists... Done
Building Dependency Tree... Done
Calculating Upgrade... Failed
The following packages have unmet dependencies:
util-linux-ng: Obsoletes: util-linux (< 2.13.1)
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
这样到错误提示呢?
