Upgrade to Feisty Fawn(Part One: Edgy first)

Three days ago, Ubuntu 7.04(Feisty Fawn) arrived. I'm still on Dapper, I'm very happy with it but decide to upgrade to Feisty because I want to try firefox2, this post says it does better hardware compat and I can't wait for next lts version that someone said "may be 2009".

I'm not sure upgrading from Dapper to Feisty directly is possible or not. But ubuntu site say "You can only directly upgrade to Ubuntu 7.04 ("Feisty Fawn") from Ubuntu 6.10 ("Edgy Eft")", so go to Edgy by

pnix@pnix-a7:~$ gksu "update-manager -c"

It will lunch update-manager with option -c(or equivalently --check-dist-upgrades). This option switch instructs Update Manager to look for upgrades. By default, the Ubuntu 6.06 LTS release will not offer that automatically because of its long support cycle and high stability. Then click the "Check" button.

then need to download about 771 M

Let's go. Hope that upgrade will be perfect
