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?

Looks like all ubuntu 18.04 installations on s390 are not working any more.
It is not an issue with z14 but z17 also fails to run a fresh installed
ubuntu 18.04.

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.
