The official announcement of Ubuntu has been yesterday and it seems to have not affected many users. Steve Langasek reported that the next version of Ubuntu, Ubuntu 17.04 will not have an ISO image for 32-bit PPC architecture as well as future versions of Ubuntu.
Something that puts an end to one of the oldest images of Ubuntu that has been in each release as well as the 32 Bit and 64 Bit version. This decision is mainly due to two reasons, although it will not cause the 64-bit PPC architecture to be forgotten or the 32-bit Ubuntu PPC users to stop receiving updates.
The reasons why the Ubuntu Community and its developers have stopped creating this ISO image are: Debian has discontinued support so Ubuntu, being based on Debian, would have trouble developing this image. But above all, the second reason is that they have barely found active users of that platform.
PPC will still be on Ubuntu but only the 64-bit version
In the last UOS that was held a month ago it was debated whether or not to continue with this platform, for which they looked for active users who could collaborate with the development or contribute their opinion. Although there are still users on this platform, the truth is that they did not find enough support to maintain the version so they decided to abandon the platform.
Although PPC users will not be able to install new versions of Ubuntu, the truth is that the old versions will continue to receive support until next 2021 after which they will stop receiving it and will have to leave the platform or have to change the operating system. Although by 2021 there may no longer be any 32-bit platform, neither PPC nor even AMD Do not you think?
