I have an old PowerMac G4 that I installed Lubuntu 16.04 on a while ago. I've been getting notifications in the terminal that 18.04 is available to upgrade, but the upgrader fails to run, saying that the package ubuntu-minimal is not available. I haven't seen any ISOs for PowerPC available, and ports.ubuntu.com doesn't have any bionic distributions available for architecture powerpc. But while searching I found this link that suggests that there is/was a version of Ubuntu 18.04 for PowerPC. Is this just a pre-generated page, or is there somewhere I can get Ubuntu Bionic for PPC?

  • Lubuntu 16.04 LTS is EOL, as being a flavor it came with only 3 years of support. All 32bit PPC support ended in April-2019 (3 years, thus MATE, Lubuntu & supporting releases for PPC ended support, as well as Ubuntu 14.04 LTS having 5 years of support). 18.04 is only available for ppc64el or the 64bit PPC which will not run on powerpc mac boxes. – guiverc Mar 20 '20 at 7:56
  • I've already answered this question here, alas I can't find it... ppc and ppc64el are in the same family, but unlike x86/i386 and amd64/x86_64 they have far more limited compatibility as performance was key with pcc64el and backwards compatibility was dropped if performance took any hit (x86_64/amd64 aimed at being backward compatible which is why it succeeded, instead of intel's ia64 failed 64bit architecture). Mac switched to amd64 anyway. – guiverc Mar 20 '20 at 8:20

Lubuntu 16.04 LTS is EOL (https://wiki.ubuntu.com/XenialXerus/ReleaseNotes/Lubuntu http://lubuntu.me/xenial-released), as being a flavor it came with only 3 years of support.

All 32-bit ppc support ended in April-2019 (3 years of support only is provided for flavors like MATE & Lubuntu which had PPC support) and Ubuntu 14.04 LTS which also had PPC support with its 5 years of standard support ended at the same time

18.04 is only available for ppc64el or the 64-bit PPC which will not run on powerpc mac boxes.
