My Ubuntu version is 11.04 and I wanna upgrade it to 12.04.
But for this purpose I have to re download my installed packages.
How can I reach to this purpose without downloading them again?( I have a ISO Ubuntu 12.04 whom I can burn it on a disk. )
I search about it and I found a way which I'm not sure about it.
The mentioned way is :
dpkg --get-selection > package_list
dpkg --set-selection < package_list
What is your opinion about it?
are you believe that it can reach us to that point?
