New version of ubuntu, named “Hardy Heron”. With the old version 7.10 using so perfectly, It’s really not so easy a decision for me wheather to upgrade it or not. Besides, as I’m installing and uninstalling so reagularly, the system has already been mess. I get no idea if the system can be upgraded soomthly, that means, if any problem occured durring the process, I have to reinstall the whole system, that could be a nightmare!
Whatever, if you want upgrade you ubuntu, please check this issue-https://help.ubuntu.com/community/HardyUpgrades
