今天安装软件的时候，第一次安装软件到一半，我点取消了，然后到第二次安装软件的时候，系统显示：
A problem that we were not expecting has occurred
Please report this bug with the error description
跟着我点了细节里面，显示
[PK_TMP_DIR/dir://var/tmp/TmpDir.MCq54q]
Repository already exists
然后我试安装了别的软件，结果也是大同小异，头一次都显示
A problem that we were not expecting has occurred
Please report this bug with the error description
跟着我点了细节里面，也是显示上面的那两句话，只是文件名不同而已，不清除是什么原因了。大家可以给个方法我吗？谢谢，谢谢
