This is the Image File for Ubuntu 14 PowerPC and it has been modified to boot on the Nintendo Wii.
That file will two partitions: a fat32 partition and a ext4 partition. The fat32 partition will contain the Linux loader for the Homebrew Channel.
Just flash this image to an SD Card (2GB or more needed!)

Please download the "Whiite-ez-wifi-config" when you download the .img file and you will need to get that file over to your wii. If you cant get the file over to the Linux filesystem, you will have to do "sudo nano /etc/network/interfaces" and add your wifi informantion manually. (Only V1.0 should have this issue) If wlan0 gets stuck on DOWN, this is an issue with wpasupplicant. Please downgrade to the .DEB provided. This will allow you to connect to wifi and upgrade to a stable version of wpasupplicant. wpasupplicant_0.7.3.deb whiite-ez-wifi-config-Fixed Boot Issues (v2.0)
-libc6 package and others are now stable by default due to newer kernel. (v2.0)
