升级的时候提示这个:<br>无法计算升级<br><br>An unresolvable problem occurred while calculating the upgrade:<br>E:无法修正错误,因为您要求某些软件包保持现状,就是它们破坏了软件包间的依赖关系。<br><br> This can be caused by:<br> * Upgrading to a pre-release version of Ubuntu<br>
* Running the current pre-release version of Ubuntu<br> * Unofficial software packages not provided by Ubuntu<br><br>很可能发生了一个传输问题,请稍后重试。<br><br>我想把要求保持现状的软件包卸载了,但怎么才能知道哪些软件要求保持现状了呀?<br clear="all"><br>-- <br>best,<br>henry cui<br>
