After previously hunting the Internet to build an archive of old Ubuntu MATE ISOs at https://releases.ubuntu-mate.org/archived/, I’m wondering, what is the official stance to flavour ISOs when they reach end of life?
For example, Ubuntu’s ISOs are archived at https://old-releases.ubuntu.com/releases/. Some of the flavours are there too, but coverage seems a bit spotty for some like Ubuntu MATE (which only has 19.04/19.10)
I’m looking for a 15.10 release of Ubuntu MATE for PowerPC, but it is challenging to track down on the open Internet. Were these ISOs archived/backed up to an offline server, or are they gone for good?
Also on the look out for Ubuntu MATE 14.10 amd64 to complete the archive, which was before Ubuntu MATE became an official flavour (and didn’t use Canonical’s build system infrastructure). Only 45% salvaged! Hope it turns up some day.
