I removed the package 'mp-harmattan-003-pr' by mistake while installing gcc and I can't find the correct package('mp-harmattan-003-pr') on available repos.I just found the package'mp-harmattan-001-pr' and it's not suitable on my China device.The apt-get can't work correctly now.It said ALL THE PACKAGES on my device is automatically installed and they are useless now and asked me to use 'apt-get autoremove' to remove them ALL.
