Can't upgrade Ubuntu 18.04 to 20.04 - Illegal instruction in rm #567

I'm using self-built Hyperion 4.5 (58578601d from git) on Fedora 38

While doing apt full-upgrade on Ubuntu under the emulator, I get following error in my session:

Unpacking libc6:s390x (2.31-0ubuntu9.9) over (2.27-3ubuntu1.6) ...
dpkg: error while cleaning up:

Searching for E70030000837 in issues, I found #367, but I'm not completely sure if it's related.

Can someone point how to overcome this?

If it matters, https://ubuntu.com/download/server/s390x has the following note:

Starting with 20.04 LTS the minimal requirement is z13s/z13, respectively LinuxONE Rockhopper/Emperor. zBC12/zEC12 are only supported up to Ubuntu 18.04 LTS.

Currently, there is no way to overcome this. Hercules does not support any of the zArch Vector instructions, which are being used more and more frequently in recent Linux distributions. I understand there is an effort underway to write the support for Vector instructions, but there are an awful lot of instructions to be supported, so the support may not be available for some time.

Fish-Git commented 1 year ago

Ian is correct: your problem is being caused by the fact that Hercules does not yet support the z/Architecture Vector Facility (and likely won't for quite some time yet).

As a result, I'm afraid, for now, you're stuck with using only Ubuntu 18.04 or earlier. Sorry!   :-(
