Trying to recreate, I was just able: - to successfully complete an 18.04 installation on a 22.10 host (that what I just had at hand) and - a successful 18.04 installation on a z/VM 6.4 host I selected in both cases the strongly recommended option 'Install security updates automatically'. (And don't be surprised that the installed system reports itself as 18.04.6, even if the 18.04.5 ISO image was used - there was another update needed for other architectures that led to a .6.)
Please can you share more details about the system you are using, especially the KVM host? ** Changed in: ubuntu-z-systems Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1994601 Title: [UBUNTU 18.04] Ubuntu 18.04 crashes during IPL Status in Ubuntu on IBM z Systems: Incomplete Status in linux package in Ubuntu: Confirmed Bug description: ---Problem Description--- Ubuntu 18.04 crashes during IPL with no output on the console.

It is not an issue with z14 but z17 also fails to run a fresh installed ubuntu 18.04. == Comment: #8 - Harald Freudenberger <fre...@de.ibm.com> - 2022-10-26 08:25:52 == when I use the 'advanced installation' where I am able to choose the kernel package and then choose the 4.15.0-50 generic the installed Ubuntu 18.04 comes up fine. So this issue is somewhere between kernel 4.15.0-50 and 4.15.0-194.
