Just to let you know that PowerPC support is being dropped from Ubuntu. Read the announcement from the Ubuntu Technical Board below for details.
As a result Ubuntu MATE will not release any PowerPC images during the 17.04 cycle. If you are a PowerPC user then 16.04 will continue to be supported, so that is your best option to keep your devices running until 2021.
They had a long run, rip
Kinda make sense since they're dropping i386.
There has been no announcement or decision made about i386.
Oh, my bad. Good to know thanks.
