Magento连接在升级时卡在“检查包的依赖性”上

I am trying to update my Magento 1.9.1.0 to 1.9.2.2 (stable) by Magento connect. but every time it stuck with the console message Checking dependencies of packages. I checked all file and folder permissions and they are up to mark. I also tried to set permission once again by the code magento set permission. but facing the same issue.

below are the solution I tried but not success.

I have custom admin URL, will this cause the issue?

While I successfully upgraded on local. On Server Magento is not on root. It is in /example.com

I am able to update other extensions like :
